Egg (Mario & Luigi: Partners in Time)

Yoob Eggs are eggs in Yoob's Belly in the game Mario & Luigi: Partners in Time. Yoshis that were eaten by Yoob are put inside these eggs by RC Shroobers and on a conveyor and are then put in Sunnycide's room, where he watches over them and waits for them to hatch. Upon hatching, they would be reborn as smaller, scarier Yoobs to prevent the Yoshis from helping the Mushroom Kingdom during the Shroob invasion. These eggs are known to have a weakness to water and fire, and after Sunnycide was beaten, the Yoshis inside the eggs were freed.
