Sharktopus

S-11, more commonly referred to as The Sharktopus, is the main antagonist of the 2010 Syfy movie of the same name. She first appears in the 2010 Syfy movie named after her.

History
The Sharktopus is the result of experiments gone wrong.

She first appeared in A Secret Guest, where Baby Shark and William accidentally stumble upon her cave and wake her up.

She reappears in Buds at First Bite, where she becomes annoyed by Penny wandering into her cave uninvited.

Appearance
The Sharktopus possesses the front half of a great white shark. Her eyes are completely black and her dorsal fin is curved. Her lower fins are elongated and have spikes on them. Spikes stick out of the three gills on either side of her body. On her underside is an octopus beak.

The Sharktopus's lower half consists of eight dark red octopus tentacles, each tipped with a black spike. These spikes are usually retracted, only to come out to intimidate her enemies.

Personality
While usually friendly to those that she knows, she gets mad very easily. This especially goes for those she has never met. When she isn't angry, she usually lends helpful advice to Baby Shark and his friends.
