The Happiness Stealer

While its existence has been denied by the SUI, the Happiness Stealer is rumored to be a bipedal lobster that became malicious. It's said that the Happiness Stealer can swallow an Animu whole.

Rumor
When Animu started to go missing due to SUI experimentation and other unknown causes, many sentient creatures started spreading the rumor of the Happiness Stealer: a being that feasts on Animu and Animu only, thriving for Animu blood. Whether first spread by panicked Animus or the mocking Bipedal Lobsters is hard to say, but ever since Animus generally consider it a mean mockery.
