Radical
Cyclops

Mnemonic

Picture a Cyclops wearing sneakers, sprinting right at you. It has one enormous eye in the center of its forehead and a roaring mouth full of jagged teeth. The cyclops closes in fast—those sneakers slap the ground as its single eye locks on you, mouth screaming, one unstoppable monster.
Additional thoughts
A Cyclops is literally defined by having one eye, so that pair of radicals is the core link. The mouth adds its terrifying roar, and sneakers make the image absurd and sticky—imagine the ground shaking with each sneaker stomp.
Quick recall
A Cyclops in sneakers has one huge eye and a roaring mouth.
