The ambitious bat
This bat's name is Brat. The previous illustration showed a boy with a T-shirt that said "Brat". Well, that's actually cause the boy's Brat's friend.He met Brat in a quiet cave where the boy used to hide so he can practice his yoga exercises. Brat was trying to learn how to fly at the time. He got sick of hanging with his head upsidedown for the last 2 years or so and though to give flying a shot.
So the two little guys met like any other ordinary couple - they got scared of one another at first, but soon after learned tolerance.
