My new character, Lapis, an inflatable batter (a mixture of bat and otter), and it's a GIRL.
As a batter, she can either fly like a real bat or swim like a real otter. But the thing is... she is trapped inside a ball XD, like a small inflatable figurine inside kid's beachball. It seem she neither fly nor swim but only roll or bounch to move.
As she is an inflatable critter inside a beach ball, she has a valve on the top of the ball and another one under her... well I suppose you already know where it is ^^"" (It's unknown where her old true valve used to be).
