Noggin

NOODLE

Think of what you might call a silly or absentminded person’s brain.

"Noggin" is slang for your head, but in crosswords, it often hints at a playful synonym. Here, it’s cluing "noodle," which also means head in informal speech—like when someone says, "Use your noodle!" The wordplay relies on the double meaning, where both terms casually refer to the brain or intelligence.
