Mnemonic

A fearsome beast lurks in the dark alley, growling menacingly. It opens its jaws and utters a single phrase: 'Yip!' You shine your flashlight down and discover it's only a puppy! The tiny beast was desperately trying to sound terrifying, but that squeaky little phrase betrayed it every time.
Additional thoughts
Imagine a massive shadow on the wall that shrinks to reveal a palm-sized puppy. The comedy of a beast whose only phrase is a tiny yip locks the radicals together.
Quick recall
A beast lets out one phrase — 'Yip!' — revealing itself as just a puppy.
