Tetris Tail

Baby pibble that's living in my house right now, possibly permanently, possibly temporarily, no idea what's going on with that.

But he's cute!

He doesn't have a real name...tall brother (who is his temporary/permanent owner) wants to name him "asshole", but that's mean, so I've been calling him Tetris-tail/Tetris butt.

Why? Because his tail broke at some point and healed improperly (I guess?) and looks like the Z-shaped tetris block.

Here's a comparison: [link]
