I'm shocked I didn't see that earlier

CJ and Gail are 100% right, though. I definitely think you should pick up some Neosporin WITHOUT PAINKILLER, because believe me, having a sick frog is not fun, and can take a long time to cure. If you need advice on how to apply the neosporin, and what kind of problem we've got here I can contact some people I know who are experienced with treating frog infections/ailments, and they can guide you through the process.

Definitely keep an eye on him, and the bump.
