Where do raccoons come from?

This is our conversation in the car tonight on the way home from dinner

Mary: Mom, do raccoons grow on trees?

Me (Julie): What? Raccoons? No... Mary, a raccoon is an animal

Mary: No, Mom. Raccoons. Do they grow on trees?... they are like this (holding up her hand making a small shape)

Me: Are you talking about an acorn?

Mary: No...OH!! Mom! A pine corn.

Pine corn = Pine Cone
