We call that the belly roll. Pacmans do that to shift large food down to their stomach. It's always cool to watch.

Don't feed to many pinkie though. Remember they are unhealthy and possibly dangerous if used as more than the occasional treat. Mix it up with staple foods.

Thanks for the information!
I feed him/her a pinkie once every week lol
I think I'm going to buy him/her some wax worms this time around.
That or super worms

If you feed you frog that many pinkies it will become obese and develope other health issues inclueding blindness. Wax worms are also full of fat and no calories. If you want your frog to grow fast you're going about it the wrong way. Your frog will develope health issues early in its life and this can be expensive or heart breaking. 1 pinky a month is good no more. Wax worms should be treats and super worms like meal worms which is basically what they are can cause impaction because the exoskeleton is not digested by your frog. There are much better food sources that you can give your frog and he/she will grow fast. All you have to do is feed your frog daily with a diverse diet that does not inclues such fattening items except once a month. Believe me your frogs life will be short if you intend to feed all fat and empty calories with no protein and shells that can't be digested. Take the advice. Its a living creature it will grow as long as its taken good care of.

Mammalian proteins are difficult for amphibians to digest. Avian proteins are easier, that is why some folks feed baby chicks (PLEASE only do this if your frog is a full grown adult and the chick is small!!!).
We have given our frogs small bits of chicken livers as a treat. They LOVE it and digest it well, but ONLY as a treat!!

Good dietary staples (Fed regularly): Earthworms, crickets, and cockroaches

Bad dietary staples (Fed as a treat or recommended): Rodents, amphibians, reptiles, feeder fish, and worms excluding compost or soil earthworms (superworms, mealworms, butterworms, waxworms)

Ivory is right about them not being able to digest or process proteins and tissue derived from vertebrates so should not be fed more than once a month. Although pinkies are nutritionally rich, they are also fatty and cause complications if fed more than advised.

There's a few other good dietary staples besides the ones I listed above, but they aren't as available and can be higher in price. Hornworms, locust, etc.

Earthworms (soil or compost) - Night crawlers, and red ringed earthworms are a great staple for pacmans. Up keep is very easy, store them in a fridge. They contain a very good calcium: phosphorus ratio and a excellent protein: fat ratio. Very easily digestable as their invertebrates. Crickets - soft-body, contain some nutitional value if gutloaded, cheap. Cockroaches - Dubia, Blatta Lateralis, etc - the alternative to crickets, research them and you'll see why.

Superworms, mealworms, and butterworms - their exoskeleton is hard and contains Chitin (A compound these animals don't come across very often in the wild, and is hard for them to digest). Not easily digestable, Grif is right. Wax worms - a treat at the most, very fatty and contain almost no nutritional value for your frog. By the way, all these worms mentioned above don't have a good calcium: phosphorus ratio and contain a high percentage of fat with little protein.

Continued from above post...

I should note that if you were to ever feed your frog a amphibian or reptile that it would have the possibility of carrying diseases. These foods should always be avoided, the only time you would ever have to provoke a feeding response with one of these vertebrates is if you owned let's say like a wc C. Cornuta. Even then you would still be able to force feed before reaching the conclusion of feeding one of these. Or get them to eat a rodent letting them off feeding for a week to get them hungry, they won't avoid food then in the right conditions. Also feeder frogs could secrete poisons into your frog, or as mentioned the diseases those frogs or reptiles adapted to that your frog wasn't ever exposed to.

Feeder fish, should almost always be avoided (Especially goldfish). If you are to buy feeder fish as an occasional variety diet, make sure you buy from a reputable fish store that captive breeds all their fish and confines all of them in clean environments (Flush them of parasites, etc.). Feeder fish that are recommended would be: Guppies, minnows, and shiners contain good nutritional value.

All the above diets (Amphibians, reptiles, feeder fish) have all been known to carry diseases and parasites and that's why they're are almost always avoided.
