Darn You, Scrat!
Animals present a surprising number of difficulties for mechanics. It is possible for them to cause a variety of problems, ranging from being wedged into places they shouldn’t be to being overly ferociously protecting their vehicle against the big bad mechanic.
There was one instance in which a mechanic opened the hood of a car that hadn’t been used in a long time, only to discover that the hood and body of the vehicle were stuffed full of nuts! Someone’s friendly neighborhood squirrel had been using the vehicle as a storage facility for his or her food supplies. Darn you, Scrat!
