Hopefully the toxins from the toad won't kill your frog. When two animals are so far apart geographically, the predator often has no defense against the toxic prey item. That's the reason Cane toads are such a problem in Australia. The only herps I know of that can eat Bufo americanus safely are garter, water, and hognose snakes that share range with the toads. Probably American bullfrogs too, but I've never seen any concrete data on those...

Even if you get lucky and the frog isn't harmed by the poison, frogs and toads are a bad idea since they carry parasites and other diseases that can easily pass to your frog.
Not only is the poison that Bufo Americanus posseses not dangerous to Pacmans, other amphibians are part of the pacman's diet. Even though the american toad is never naturally eaten by the pacman, the pacman is still built to eat other amphibians.
