Mechanics at a local repair shop in Dedham, Massachusetts, were surprised by what they found under the hood of a customer's car brought in due to a "check engine" light on Tuesday morning.
A groundhog was "tucked away" in the vehicle's engine compartment, according to the Dedham Police Department.

An animal control officer from the Dedham Police Department, who was called to the scene, "was able to free the animal and send it on its way," police added
