If you where looking for extreme color and would've considered shipping I would've suggested a tomato frog. They get about fist sized have a pretty big mouth and essentially aren't too different behavior and habitat wise than a Pacman. Good luck with Bully though man and here's a quick googled image of a tomato frog.
I ended up picking up the little bull frog today! Can't wait to see him turn in to a monster, hard to beleave they get bigger that my 7-8 inch horn frog!
