Pacman yelping?

The feet on the bottom make little squeak sounds. But if your unsure at first its most likely your frog.

if that is a male and he is calling he will have nuptial pads check for these. if you don't see that would mean you have a female or he is still too young to call, and what you heard wasn't a call. and if he is a male and have nuptial pads try to play audio of other males calling, it is so cute when they respond
