Uni-Armadillo Yummy

The Uni-Armadillo Yummy is an armadillo Yummy augmented with the features of a sea urchin that was created by Mezool using a Cell Medal on a sleepy Gamel. The Uni-Armadillo Yummy acts on a scheme to cause insomnia on those he hits with his spines, until the desire to sleep becomes strong enough that he puts everyone to sleep and gets full of Cell Medals. Although he manages to withstand Kamen Rider OOO's attacks with the Medagabryu, he is destroyed when the Kamen Rider eventually gains the upper hand as Takauba in conjunction with the Medagabryu.
