Mnemonic

Your leg starts twitching the moment you spot a sign that reads 'Bounce Zone!' Unable to resist, you hop forward — your leg launches you skyward, and you keep bouncing past the sign like a spring-loaded kangaroo, each leap higher than the last.
Additional thoughts
Picture a neon sign at a trampoline park; your leg acts on instinct the second it reads the invitation. The compulsive bouncing cements the idea of hopping.
Quick recall
A leg sees a sign saying 'Bounce Zone' and can't stop itself from hopping skyward.
