Mystic Forest

Mystic Forest is the fifth main world that Mario chases Donkey Kong through in Mario vs. Donkey Kong. This world's theme is a forest one, and the world contains a number of gimmicks, as well as the wide variety of enemies that appear throughout the levels. This world introduces the conveyor belt gimmick, Cannons, Bob-ombs and their usage in breaking blocks. Monchees, Bats, Sleeping Spear Guys, and Fire Piranha Plants also make an appearance in this world, and its plus counterpart is Mystic Forest Plus.

5-1
This level's opening demonstration involves Mario using a conveyor belt switch to change the direction, duck while on the belt, and make it past a wall. This level introduces the addition of switches to conveyor belt mechanic.

The first half of this level has several conveyor belts and a pair of switches, with the key on the other side of a wall. The door is right below the furthest away switch. Since the key is on a platform with only a ladder to access it, the key must be taken around to get to the door. Mario must switch the belt's direction to get under the wall and on to the key's side. He then must send the key on to a higher conveyor belt, switching the direction using a nearby switch to get the key to ground level on the other side, where it can then be reached, grabbed, taken under the wall and used to unlock the door.

The second half of this level is vertical, scrolling up as Mario climbs higher. It has a single spring, several ropes, conveyor belts and a single switch on ground level as well as one near the top. There are also several Fire Piranha Plants that hinder Mario as he climbs.

The high score for this level is 28,500.

Presents

 * Red Present - In the first half of the level, this present is above the switch that is furthest away from Mario's starting point.
 * Yellow Present - In the second half of the level, this present is to the immediate left of the second Fire Piranha Plant on the right side of the screen, between it and a rope. Mario can grab it by reaching out while on the nearby rope.
 * Blue Present - In the second half of the level, this present is right underneath the platform that the only Fire Piranha Plant who is not to the sides is on. It can be reached by using the conveyor belt to take Mario right into it as he ducks, or by performing a back flip from one of the conveyor belts below.

Enemies

 * Fire Piranha Plants

This level's opening demonstration involves Mario (who is currently using a hammer) walking toward a ladder, throwing the hammer into the air, climbing the ladder to reach the above platform, grabbing the hammer, and defeating a nearby Sleeping Spear Guy with it.

The first half of this level has several ladders and many Sleeping Spear Guys throughout, with several hammers at Mario's disposal to defeat them. Additionally, there are several blue and red switches that activate a blue ladder, platform, and blockade or a red platform and its own blockade. Due to the layout of this part, Mario must traverse to the top of the area, head to the eastern side, climb down, grab the key after hitting a blue switch to make it reachable, and then hit a red switch to open the passage to the door, all while avoiding the Sleeping Spear Guys scattered throughout the level.

The second half of this level has a pair of Monchees, several ropes, two yellow switches and a platform; and a red switch and two red platforms. Mario must make use of both of the Monchees to make it across a spike pit where the Mini Mario is on the other side; one of them, however, must be manipulated with switches so it falls off a yellow platform to fall from red to then land in an appropriate spot.

The high score for this level is 29,000.

Presents

 * Red Present - In the first half of the level, this present is above the highest and furthest to the left Sleeping Spear Guy, near the blue platform. It can be accessed by hitting the blue switch early.
 * Yellow Present - In the second half of the level, this present is in between the furthest and second furthest to the right ropes,
 * Blue Present - In the second half of the level, this present is above the western yellow switch.

Enemies

 * Sleeping Spear Guys
 * Monchees

This level's opening demonstration involves Mario using a blue switch to release a key on to a conveyor belt. He then hits a nearby conveyor belt switch to stop the key's falling on spikes to the right, and the key eventually falls off the other side of the conveyor belt.

The first half of this level is divided into two halves by blocks in the middle of the area. The only way to get to the other side is to use one of the three conveyor belts in the middle. There is a pair of switches as well as a red and yellow one. There is a red platform (which the door is on), ladder, and block and two yellow blocks. Mario must use the conveyor belts and red/yellow blocks as he did in the demonstration to manipulate and get the key to the door.

The second half of this level has two Bob-omb dispensers, a red and blue switch with a red platform above some spikes, and several blue blocks above a horizontal blockade. There are also several red and breakable blockades. Mario must use the Bob-ombs to break the blockades between him and the blue switch. Once he activates the switch, he can destroy the remaining blockades to reach the Mini Mario.

The high score for this level is 27,500.

Presents

 * Red Present - In the first half of the level, this present is to the immediate left of the eastern yellow block.
 * Yellow Present - In the second half of the level, this present is in the topmost-left part of the area, reachable for Mario via backflip when the blue switch is active.
 * Blue Present - In the second half of the level, this present is above a red platform, accessible only when the red switch is active.

Enemies

 * Bob-ombs

This level's opening demonstration involves Mario climbing some ropes to get attacked mid-climb by a recently released bat, which results in his falling after getting choked briefly, landing on his back.

The first half of this level has three vertical moving platforms as well as a conveyor belt and a single switch for them. There is also a red blockade of two blocks before the door, a red block right above a conveyor belt, and a blue switch, all in the lower half of the area. In the higher half, there are many ropes and a pair of bat caves that release bats that hinder Mario as he climbs the ropes. The lower half of the area is divided by a vertical line of blocks.

The second half of this level has two bat caves and five Cannons (which are all on platforms to the side) that fire Cannonballs, both enemies that can hinder Mario as he climbs the many ropes in the area. Like the first half, this area is a vertical one, and at the leftmost top is a Mini Mario.

The high score for this level is 26,000.

Presents

 * Red Present - In the first half of the level, this present is above some spikes, to the left of a rope.
 * Yellow Present - In the second half of the level, this present is to the left of the higher bat cave.
 * Blue Present - In the second half of the level, this present is above the lowest cannon in the level.

Enemies

This level's opening demonstration involves Mario's using a switch to reverse the direction of some vertical moving platforms, which he then uses to reach a higher spot.

The first half of this level has a pair of springs and three switches which controls three conveyor belts and vertical moving platforms. There is also both a red and yellow switch, which controls a red blockade, a yellow platform of blocks that enables access to a door, and a yellow block which blocks the other area via the lower conveyor belt. Mario must activate the yellow switch to create a platform under the door. Then, he should have the platform move up so he can reach the door with the key.

The second half of this level has five Sleeping Shy Guys and a pair of Monchees. There are also six conveyor belts, a pair of springs, and several ropes and three hammers that assist Mario in his climb and against the aforementioned enemies. Near the top, the Mini Mario is guarded by a Sleeping Spear Guy who must leave its position or be defeated in order to finish the level.

The high score for this level is 24,500.

Presents

 * Red Present - In the first half of the level, this present is underneath a pair of blocks with spikes on them, above the highest conveyor belt.
 * Yellow Present - In the second half of the level, this present is below a closed-off section a Monchee walks inside, above some spikes.
 * Blue Present - In the second half of the level, this present is above a closed-off section a Monchee walks inside, to the left of a Sleeping Shy Guy.

Enemies

 * Sleeping Spear Guys
 * Monchees

This level's opening demonstration involves Mario's jumping and throwing a Bob-omb through a platform to make it destroy the blocks around the ladder that would allow him to reach the Mini Mario.

The first half of this level has a blue ladder, two platforms and switch. Some red blocks prevent Mario from riding the moving platforms. There are also a pair of springs surrounded by spikes in a higher section, disintegrating bits of ground and Donut Lifts, as well as several moving platforms. There is a spike pit at the bottom of the area. Mario must activate the blue switch to be able to access the door with a key.

The second half of this level has breakable blocks scattered in the lower part of the level, three blue ladders, two blue platforms and a blue switch (at the very top). There are five cannons that hinder Mario as he climbs to the blue switch and a single Bob-omb dispenser that Mario will have to use to reach the Mini Mario.

The high score for this level is 26,500.

Presents

 * Red Present - In the first half of the level, this present is above some spikes that are in between two springs and several ropes.
 * Yellow Present - In the first half of the level, this present is to the left of some spikes and is above a moving platform's route.
 * Blue Present - In the second half of the level, this present is to the left of the highest blue platform.

Enemies

 * Bob-ombs

5-MM
This level's opening demonstration involves Mario throwing up a Bob-omb next to a breakable blockade that is stopping the Mini Mario toys from following him on the platform above. Mario (from the platform below) then leads them away from the blockade so he can lead them past where the blockade once was after the Bob-omb destroys it.

This Mini Mario level has several ropes, a blue switch and mini staircase of blue blocks, as well as a pair of normal ladders, springs and Bob-omb dispensers. There are breakable blockades scattered throughout the level that must be destroyed with Bob-ombs in order for Mario to finish the level at the topmost middle section of the level.

The high score for this level is 12,000.

Letters

 * T - This letter is behind the first breakable blockade that is encountered.
 * O - This letter is underneath the platform of blocks the Toy Box is on. It can be accessed by either having the blue switch inactive (allowing entrance to the passage from the right) or by having the breakable blockade destroyed (allowing entrance to the passage from the left).
 * Y - This letter is to the right of a blue switch and to the left of a mini staircase composed of breakable blocks.

Enemies

 * Bob-ombs

5-DK
This Donkey Kong fight takes place in an area with five conveyor belts to each side and DK on a high platform in the middle with a switch on it. DK throws red variants of Bob-ombs (that work the same as the original) on the conveyor belts to the side to try to hit Mario. The Bob-ombs carried by the conveyor belts move erratically as DK switches the direction. Mario must pick up and throw these Bob-ombs at DK when the chance arises (or just have them explode within DK's range) four times in order to defeat him. DK throws these Bob-ombs more erratically and often each time he gets hit. The night background now used here is also recycled as the background for the entirety of Mystic Forest Plus.

The high score for this boss is 22,500.
