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 and he'll watch over them and wait for them to hatch and 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, after Sunnycide was beat, Yoshis inside the eggs were freed.
