Derpshark Mouse

An eccentric type of fish, totally oblivious to everything in the ocean, even foregoing eating and sleeping if something shiny happens to catch their eye. You know when one is nearby based on its whale-like howls and echoing cries (it thinks it's a whale).

Long and loud howls can be heard wherever Derpsharks congregate. There is nothing to fear, however, as they are relatively harmless to others. But it is wise to keep your distance when they gather, because they might not notice you nearby and overwhelm you with their massive crowd!
