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. They only appear in one level, 4-4: Neuron Jungle. 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 defeat. Certain Neurons will also be nestled in inconvenient areas, blocking places and fruits off with their tall bodies. They have a spiked, underwater counterpart called the Sea Cactus.
There are four main types of Neurons:
They have eyes on the top of their heads covered by light blue and purple eyelids. When Yoshis touch an eye, it retracts into the Neuron. When Yoshis cause them to move, they make a unique deep buzzing sound that sounds as if they are shouting "Nyoro!"
