Wally's got a pretty cool mutation, he'd say.

Some members of the team are pretty unlucky. He wouldn't say as such. Yes, he's short, so what? But he's got cute little pointy ears! And, you know, he can run pretty fast...

Yeah, okay. His birth mutation might not be all that unique. But he's quite happy with it. At least he's not like Dick, who was born human...!
