Daruma Otoshi-kun

Daruma Otoshi-kun are enemies that appear in Yoshi Topsy-Turvy, found only in the sixth chapter, Tale of the Spirit of Fright. They are bird creatures with purple bodies and a beak that is a slightly darker shade of purple. Their bottoms are colored green and they have small, skinny legs and with three-toed feet. They also have small, beady eyes and a set of four spikes on their heads. If Yoshi lands on the spikes, he will take damage. They are always walking forwards, though some do so extremely slowly. They cannot be defeated by any means.
