Dream up, as a plan

HATCH

Think of what a chick does before emerging from its shell.

"Dream up, as a plan" hints at the word "hatch," which means to create or devise something, like a scheme or idea. The clue plays on the literal meaning of "hatch" (as in a bird emerging from an egg) to suggest bringing an idea to life. It’s a straightforward definition with a slight nod to the word’s dual meaning.
