Neuron

Neurons are a species featured in Yoshi's Story. They appear to be large multi-colored worm-like creatures with whiskers on the top of their heads. Only appearing in one level, 4-4: Neuron Jungle, they have proven themselves to be enemies and allies. The Yoshis can mostly use their heads as platforms to reach other places, but at times Neurons can push Yoshis off the edges of platforms to their deaths. Certain Neurons will also be nestled in unconvenient areas, blocking places and fruits off with their tall bodies.

Types
There are 4 types of Neurons:


 * Red with black spots (stays still, goes down when you Ground Pound on it)
 * Light blue with blue spots (curves after you Jump on it)
 * Yellow with magenta spots (goes straight up and straight down)
 * Pink with purple spots (stays in the air but tilts side to side)

They have eyes on the top of their heads covered by light blue eyelids. When Yoshis touch an eye it retracts into the Neuron. When Yoshis cause them to move, they make a unique sound that sounds as if they are shouting "Yobe!" or "Yobelum!" Since level 4-4 in Yoshi's Story, Neurons have never appeared in any other games.
