It's a slice-of-life about a group of monsters/creatures/cryptids in a polycule relationship and the first scene I've thought kind of goes like this

Someone trying to hand a fishfolk looking dude a pizza.

It's sniffs the pizza before opening a wider/bigger then expected mouth and snatching it before swimming away.

A vampire with a sun umbrella and shifter in a human form looks at each other.

The fish boy pops back up looking for more pizza, it gets handed another slice and stays this time.

Shifter looks up at the vampire excitedly. "Can we-!"
