This may be an odd question but oh well, if you don't ask questions, you'll never get answers, right?

Anyways, we just bought a pacman frog and have heard from a couple of people (none who have owned one before, mind you), that pacman frogs have a hook on the end of their tongue, and can really do some damage to you if they get you with it. So I did some online researching on the subject and have come up with NOTHING that either confirms or denies this claim. So, my question is, is it true? I know they have teeth, but do they have a hooked tongue? If not, is there a type of frog that does? It's got me very curious, especially since I've heard this from more than one person.

Thanks for the help!
