You can actually get pacman frogs as pets but unless you prefer pets you don't touch and are willing to spend a lot of money for an appropriate enclosure you don't want one.

Sounds like "Beelzeboot: the Canadian Satan" from South Park.

I may have the answer to this problem but first I should find out the carry weight of a cretaceous African swallow.

Pacman is an icon in the Philippines (champion boxer Manny Pacquiao) but the biggest frog here is the American bullfrog. A tiny frog lives in my bathroom, and it's about the size of my thumbnail. It sings like a little bird too1 Beautiful!
