Here’s mine:
D.B. Platypus just doesn’t fit in anywhere. Not with fish nor fowl nor beasts.
Oddball! Platypus is alone in a crowd; it’s different from every other thing around it.
Of course, Platy is infinitely cuter than poor little ol’ wormme. Woe is me. So, how about your animal alter ego. It’s probably safe to assume that edohiguma’s is a mountain bear. So tell me yours! I’ll let you know whether or not you can keep it. My decision is final; you cannot contend it with me.

They are strangely cute. Mesmerizing in fact.
IT’S A TRAP!
I can’t decide. I was a serious animal enthusiast as a kid and went through stages.
The cheetah period.
The leopard, jaguar and other assorted wild cat period.
The bat period.
The whale and dolphin period.
The owl period, especially horned owls, barn owls, and white owls.
The otter period.
At some period of angst-ridden young adulthood I remember thinking prairie falcons were really cool.
The bat period was longest, so maybe it’s bats!
But I also thought platapuses where seriously cool–not totem level cool but up there.
Can’t decide? Then yours is the legendery rhinoceres/elephant blend…the Elephino.
No penguin period?
Son, I’m disappoint!
Wait, I got it!
The sloth!
It’s an animal, and it’s one of the Seven Deadly Sins!
