Uquai

Uquai is known through legends and folklore as a huge and malicious deep sea monster.
And while they're actually significantly larger than any known feline creature (~10m/33ft long), they're really just kinda bored and want to play.
The numerous boats they accidentally capsized have a different point of view though.

Note: please do not draw on land they're a literal deep sea monster no solid land allowed thank u
(they do occasionally swim on the surface though)
