Sharktopus

S-11, more commonly referred to as The Sharktopus, is a fan-made anti-hero in the Nick Jr. series Baby Shark's Big Show!. She first appears in The Secluded Resident.

History
The Sharktopus is the result of experiments gone wrong. She used to be friendly to most people, but everyone just mocked her abnormal appearance. In her rage, she escaped to Carnivore Cove and took residence inside of a dark cave. She rarely, if ever, left her cave after escaping to Carnivore Cove. Since then, she has a strong resentment of outsiders. She also developed a strong dislike of the Baby Shark song, much to Baby's dismay.

One day, Baby and William unknowingly enter her residence, make a mess, and sing the Baby Shark song. All of this combined wakes the Sharktopus up and she demands both of them to leave. Terrified and not knowing what they woke up, Baby and William flee the cave very quickly. William gets a look at the monster while running away. He tries to tell Baby, who doesn't believe that a Sharktopus exists. Suddenly, the Sharktopus seizes Baby and takes him to her lair. Upon waking up, Baby is trembling with fear when the Sharktopus fully reveals herself to him. The Sharktopus demands that Baby cleans up her cave as punishment for wrecking it. Baby, still trembling, begins cleaning. But when he hits her by mistake, she really tries to hurt him. Baby begs to be let go, saying that his family and William will be worried about him. The Sharktopus calms down, realizing that Baby's family would be worried about his disappearance. Baby, relieved, asks why the Sharktopus is so angry all the time. After the Sharktopus explains her backstory, the two call a truce. William and Baby's family show up to rescue him.

Ever since the truce between her and Baby, Sharktopus has returned to public life in Carnivore Cove. She has implemented an almost impenetrable security system in her cave to avoid her cave being ruined.

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.

The Sharktopus is massive, being ~25-30 feet.

Personality
The Sharktopus is very grumpy and hates uninvited guests in her lair. If anyone makes a mess of her lair, she makes them clean it up. She also hates the Baby Shark song, which Baby dislikes about her. She also uses intimidation to get her way, which proves very effective. She never tries to intentionally cause harm to someone.

After having a conversation with Baby about her anger issues, she managed to calm down mostly. However, she still isn't afraid to lash out at others.
