Before they adopted the name 'Pacman', their English name was and still is 'Horned Frogs'. Just to be more specific, try labeling a picture to tell us what pacman you are looking for besides the Fantasy to help you identify. You could be talking about a Chacoan Horned Frog (C. cranwelli), Surinam Horned Frog (C. cornuta), Argentine Horned Frog(C. Ornata), Caatinga Horned Frog (C. joazeirensis), and Brazilian Horned Frog (C. Aurita).
