The Mutant Squid is a common Earth squid, which was mutated by Dr. Animo in the episode Divided We Stand. Its main use was to attack people and defend Dr. Animo's base. It used its tentacles as hands to perform various actions. It had white spikes, pale red/brown skin, and slightly pink suction cups on its tentacles. Its entire body was not shown, but instead its shadow was shown in addition to its tentacles. It was defeated by Upgrade.
