If you cast a Squirrel spell that depicts a squirrel (as most do), you'd get two acorn counters: one when you cast the spell, and another when the spell resolves and the Squirrel enters the battlefield.

You retain all acorn counters in your stash until you spend them, even if you lose control of Acornelia.
