Carrefour special offer

There today, live flogs (sic :smiley:), a possible bargain at 39NT each. Or 3 for 100NT. Locals know them as ‘field chickens’. We watched them for a while, flopping around in a few inches of water next to the fish tank, and wondered why they don’t just jump out. Are they too big and fat, or are the tendons snipped to stop any such frog-hopping?
