It would be cool if you tamed these like otters. It should be a passive tame, where you kill meganeuras and drag their dead bodies to the frog and feed it.
Beelzebufo
One of the island's most useful amphibians, the beelzebufo can create cementing paste in its stomach simply by eating insects. Incredibly fast when hopping, its jumps can traverse vast expanses at the cost of little to no stamina. The beelzebufo can swim especially well and is one of the few creatures that can cause torpor using its attack. While it may be a little difficult to tame safely, many survivors consider it an especially useful addition to their tribes.
