Egg (Mario & Luigi: Partners in Time)

Eggs (also referred to as Yoshi eggs) are enemies in Yoob's Belly in the game Mario & Luigi: Partners in Time. Yoshis that are eaten by Yoob are put inside these eggs by RC Shroobers and placed on a conveyor. They are then put in Sunnycide's room, where he watches over them, where it is implied that they will hatch into monsters as well. These eggs are known to have a weakness to water and fire, and after Sunnycide is beaten, the Yoshis inside the eggs are freed.
