Amphibians can fascinate. Take, for example, Toad. He and common hopping Frog Are profiled in this ode. How can one tell the difference Twixt one and twixt the others? They're of Anura order Which might suggest they're brothers; Yet Froggy's coat is shiny Whilst Toad's is almost matt, He has no hint of slimy Nor is thin, he's rather fat. His mouth does not boast gnashers Whereas Froggy has his teeth Within the jaw, along the top, He's toothless underneath. You're unconvinced? You might decide To try 'leg swallow' check. If smooth without a ridge or bump And slip slides down your neck, 'Tis Frog, not Toad whose outer skin Is massed with many bumps Which makes it hard to chew right through Those gnarly gristly lumps. So, either book the Eurostar And take yourself to France To sample cuisses de grenouilles, Or "Vive la Difference"!
