Giant Land

Giant Land (more commonly known as Big Island) is the fourth world of Super Mario Bros. 3.This world contains six levels, three Sledge Bros., two Fortresses, and four Toad Houses. Everything in this world is huge, including the ? Blocks and Goombas, hence the name. Cheep-cheeps are the only exception to this. This island is shaped like a giant Koopa Troopa.

The Koopaling in charge of Giant Land is the comparatively-small Iggy Koopa.

In The Adventures of Super Mario Bros. 3, it is revealed that Prince Hugo the Huge is the most recent king, who probably replaced the one in the game. Madzilla also lives here.

The Giant Land's reference is Asia

4-1
This is the first level of world 4, and introduces many huge versions of otherwise regular enemies like Goombas or Koopa Troopas. However, their size does not improve their stamina or other physical stats, so they can just be defeated like their smaller counterparts. The player will also encounter some big ? Blocks, which can be hit just like normal ones. The level is plain-themed.

4-2
This level is similar to the second level of Water Land. The whole stage rises up and sinks down frequently, so some parts of the stage may submerge occasionaly. If Mario falls in the Water, a Cheep Cheep will come by and try to hurt him, so the player should get out as fast as possible. The Cheep Cheep can be defeated with a well aimed Ice Block, but it will respawn after some moments, and it cannot be defeated permanently. The goal is reached through a Warp Pipe at the end of the level. If Mario collects at least 20 coins in this level, a White Toad House will be available.

4-3
This level introduces the Sledge Bros. which is just a bigger version of a regular Hammer Bro.. Just like their smaller versions, they throw hammers at Mario, but they are also capable of a shockwave-creating jump that will stun Mario, making it likelier to get hit by a hammer. After crossing a plains section, the player will get access to the second part of the level through a Warp Pipe. The second half features many Buzzy Beetles, as well as some bottomless pits which have to be jumped over using a Paratroopa as stepping stone sometimes.

Fortress
The first fortress of Giant Land features a new type of enemy: The Hot Foots. These flame-like enemies lurk on top of candelabra, waiting for Mario to turn his back to them. When unobserved, they hop off of their resting place and follow Mario, until he turns around. During his traverse of the fortress, Mario can uncover a secret underground section of the castle, filled with Boos and Dry Bones, through a Warp Pipe. At the end of the caste, Boom Boom awaits.

4-4
Lakitu appears in this aquatic level. Mario should stay where he is in the first part, then stomp the flying menace when he gets close. Only Frog Mario or small Mario (with very good timing and aim) can get past the current-spewing pipe to get to a secret area with two P-Switches and a ton of potential coins. Other Mario varieties must stay low to dodge the Spinies that Lakitu will hurl into the depths, but Fire Mario can dispatch them easily.

4-5
To win in this level, Mario should use a Koopa to grab the power-up from the ? Block, then continue on his merry way. Missile Bills will home in on Mario, and if they pass him, they will turn around for another shot. Soon, a high block will be seen. Mario must leap off a Bill to reveal a Magic Vine. Then hop off a tall Bill Blaster to reach it and go for a climb. At the top, a pipe to a secret room awaits. Mario should not hit the P-Switch yet, but first hit the ? Block for a Tanooki Suit. This suit works like the Super Leaf in flying capabilities, but if Down on the D-Pad and the B Button are pressed, Mario will become an invincible statue for a short time. Mario should hurry out after the P-Switch is hit, as many Silver Coins will appear outside. After a Pirahnacus Giganticus, the pipe to the exit awaits.

4-6
First, in the huge box of blocks, a 1-Up is concealed. Afterward, the Magic Door, if entered, will return everything to normal. Near where the 1-Up was found on the giant side, on the normal side there is a Starman. There is no difference between the two, except the large enemies are harder to dodge. Raccoon Mario can fly into the clouds to find coins on both sides, but on the regular side a 1-Up is hidden. In the wooden blocks soon after, another Starman is hidden, and right by, against a pipe, a few invisible blocks are concealed, one with another 1-Up. Another big/little door is nearby, and so is the exit.

Fortress
The Donut Lifts here might be very dangerous. Mario must jump up and down on them to keep from falling. A secret is here after the lava stretch. In the narrow corridor, a block has a P-Switch inside. The Switch will expose some Silver Coins. In the middle of them, Up on the D-Pad should be pressed to enter a secret room. The platforms here are all different. The ones with arrows on them will automatically go a certain way, but the one with the exclamation point, whenever jumped on, will change direction. Skillful use of these and the many pipes will lead Mario to a pipe to a secret room, where, starting at the exit pipe, invisible blocks form a staircase to a block with a 1-Up. Afterward, a big ? Block has three 1-Ups, and Raccoon or Tanooki Mario can fly up to a little room above with quite a few coins. The exit pipe leads right to where Mario left off, and afterward is the fight with Boom Boom.

Airship
This Ship may be considered easy because all the cannons are Rocket Engines. Mario must really watch out for these. The boss, Iggy Koopa, is no harder than Larry or Morton.
