Croaking and Angry Pacman Frogs

[John]

These are some very surprising videos from youtube.

Here's a growling Budgett's frog:
YouTube - Deadly Mexican Staring Frog of Southern Sri Lanka

And a growling Fantasy Frog (Ceratophrys cranwelli hybrid with C. cornuta)
YouTube - Pissed off Fantasy Frog in HD. Volume up.

(Note to anyone watching this - don't use small gravel like that with your frogs because they can swallow it accidentally and it can cause a blockage in their gut, known as an impaction, which can kill your frog)

Real cool video, I do like seeing the defensive response of the pac-man. It blows up like a toad, but then adds hissing and biting to the mix.

Budget's don't even look real. They look like a cartoon.

The second Pacman video is fantastic - in between screams he's actually growling.

It didn't work when I clicked on it, The rest worked fine.

Is this normal pac-man behaviour or just when taunted?
