Miss Warp
From the Super Mario Wiki
A Miss Warp jumping.
Miss Warps were helpful, round, egg-like people found in Yoshi's Story. They all slept on the ground, but, when woken up by a Yoshi, they are helpful. There are four Miss Warps in each level in the game, all numbered from 1-4 depending on their distance from the start of the level. When a Yoshi wakes two or more up, the Miss Warp, when jumped upon, will throw the Yoshi to the next available Miss Warp in sequence.
So far, Miss Warps have only appeared in Yoshi's Story.
