Fun froggy fact: Strawberry poison-dart frogs get their toxins from their environment, so the fact that they can just stack with the other froggies means there is zero toxicity in Froggy Land.
The frogs stack to defy god; Frogs were not meant to be stacked: yet they do it regardless of their creators intentions; the frogs stack in their arrogance not knowing of their grizzly demise, like Icarus who flew too close to the sun, they will be the architect of their own doom.
