Super Mario World
In Super Mario World, Red Eggs have an orange tint to their shell. They hatch into red Baby Yoshis. When adult Red Yoshis lay eggs, the egg is usually a Red Egg.
Yoshi's Island series
Red Eggs also appear as throwable objects in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3 and later Yoshi's Island DS and Yoshi's New Island. If a Green Egg recoils two times off a wall, it turns into a Red Egg which Yoshi can catch and add to his stash of eggs. However, if the egg recoils too much, it falls off-screen. Red Eggs can also be obtained from red Egg Blocks, though unlike the green Egg Block, Yoshi only gets one egg. When Red Eggs hit an enemy, two Stars appear where the impact was.
Yoshi's Crafted World
Red Eggs return in Yoshi's Crafted World, where they are once again created by a Green Egg hitting a wall twice before being recollected or hitting an enemy. They give three Hearts to Yoshi when used to defeat an enemy, with the Hearts automatically being collected upon spawning, unlike in prior games where the Stars had to be manually grabbed.
