Mushrooms (Fat Cat)

 refer to enemies with pink coloured heads and leafy green bodies from the game Fat Cat. In most levels, they simply move around, trying to prevent the cat from passing, while other times, they may be stationary, spraying bullets from its head.

Although the mushroom's health is represented by a bar like many of the bigger enemies, it takes less time to destroy as opposed to other enemies with health bars in the game. When destroyed, they typically leave food behind for the cat to pick up.
