Slime Tile

Slime Tile is the main tile in Alchemist Lab, the only exception being the tiles under items. They come in blue and red varieties, and a player cannot walk from one color to the other. The only way to change colors is by being splashed by a Slime Beast, or by leaving the lab. They can be created outside the labs by killing Slime Beasts. The slime tiles are not affected by any land's rules, and the Slime Beasts can move on them.
