I've tested it out before against other amphibians in battle arena and here are the results
Toad vs Dwarf salamander = Toad wins
Toad vs Newt = Toad wins (again)
Toad vs Pinewood tree frog = toad wins (again and again)
Toad vs Bullfrog.. It's pretty much a 50/50. If the toad managed to dodge it's tongue range then bullfrog is dead, but if the toad didn't it dies.
