Shark, Narwhal and dolphin.

(These are just their temporary names lol)
To lazy to write the speech bubbles so here’s what they’re saying.

Dolphin: SHARK! WHY DID THE SEA EEL CROSS THE REEF?
Shark: you tell me another one of your jokes and I’ll maul you alive..
Narwhal: Guys! Let’s all be friends! Yayayaya!
