Toadwood Forest

The Toadwood Forest is a forest located in the Mushroom Kingdom in Mario & Luigi: Partners in Time. The Shroobs use the forest to harvest vim from Toads to use as fuel. Monsters such as Koopeleons, Boo Guys, and Elasto-Piranhas reside in the forest.

Geography
Toadwood Forest is located between Bowser's Castle and Peach's Castle, according to the map for the Mushroom Kingdom. In universe, the forest is presumably used for easy travel between the two castles.

History
During the Shroob invasion, Toads are abducted and placed on the forest's trees which then drain the vim, their life force, out of them, slowly killing them in the process. The vim is transferred through the roots of the trees to the Vim Factory, a huge Shroob-created building built in the middle of the Toadwood Forest. Once there, the vim is altered by Swiggler with chemicals and turned into fuel for the Shroob UFOs.

The Mario brothers and their baby counterparts travel to the Toadwood Forest of the past after the Cobalt Star shard retrieved from Baby Bowser's Castle opens a time hole to that location. As they journey through the forest, they encounter multiple Toads strapped to the trees. They eventually reach Toadiko, who reveals what happened to her, Toadbert, and Princess Peach after they traveled to the past and tells the Shroobs' plans to the Mario brothers. Before Toadiko can finish, five Shroob UFOs attack and turn her into a Shroob mushroom. However, the brothers manage to evade the attacks. After burning the trees blocking the way to the Vim Factory, they take a Warp Pipe to bring them closer to the factory.

In the next area, the brothers and the baby brothers activate two switches to raise the platforms in front of the factory's entrance, allowing access.

Layout
In the first area of the Toadwood Forest are stumps that the adult brothers can throw the baby brothers into. Inside are ? Blocks that contain coins or items. Some stumps contain enemies as well. Trampolines are used to get out. At the end is an area where the baby brothers need to go underground to hit six fire blocks. After each fire block is hit, a fireball shoots out of a long stump and enters an Empty Block above ground. The adult brothers need to hit these blocks to combine the six fireballs into one large fireball at the center of the area. After hitting the block the large fireball is in. It launches and clears a path to the Warp Pipe that leads to the Vim Factory.

In the second area are pits filled with thorns. To cross them, the baby brothers must use a block to control the floating panel while the adult brothers are riding it. ? Blocks are found above safe ground and barriers over the largest pit. Warp Blocks are found on the other side to reunite the brothers. There are two statue that require Simultaneous Blocks to be hit by all four brothers to activate them. After activating both, they can enter the Vim Factory.
