I looked under the hood of my car and did not see any chipmunks or other small creatures. Please tell me where I can get one of these. I promise all the walnuts they want.

Squirrels love to nest in the air filter compartment. They will fill it with seeds and nuts which chokes the car to a stop, meaning you’ll have to start looking up car transport quotes. You never know what might be under the hood trying to stay warm.
Those are chipmunks not squirrels
