Sunnycide

Sunnycide appeared in 2005 video game called Mario & Luigi: Partners in Time. Sunnycide is an egg-like Shroob monster that was created during the Shroob invasion of the Mushroom Kingdom in Mario & Luigi: Partners in Time, in case something went wrong with their plan of preventing the Yoshis from helping the Mushroom Kingdom. Sunnycide's name is a pun on the term 'sunny-side up/down', ways to fry eggs, and the suffix -cide, meaning "to kill." It was stationed inside Yoob's belly, where it served as the guardian of the Shroob-created eggs holding the captured Yoshis. Sunnycide would watch over these eggs until they presumably hatched and became more monstrous Yoobs to conquer Yoshi's Island. Sunnycide also guarded the exit to Yoob's stomach, preventing anyone from leaving it. Sunnycide acts as the last enemy fought on Yoshi's Island, and the game's sixth boss.

Sunnycide resembles a large pink egg with green spots (similar to Yoob's egg). The shell is cracked through the middle horizontally, creating a mouth and separating Sunnycide's body into two halves. Two eye-stalks sprout from the top of the egg, while two tentacle-like arms and two round feet emerge from the bottom half. Inside the mouth is Sunnycide's weak spot, a large bump resembling an egg yolk partially covered with a bandage. After the Mario brothers helped a band of Yoshis through the factory in Yoob's stomach, the heroes eventually enter the lair of Sunnycide. It immediately attacks the Mario Bros., though Luigi keeps trying to run away but is repeatedly blocked.
