Run to the car and drive off

From Create Your Own Story

You're not going to stick around with your angry uncle. You run to the car, with the purpose of driving it away, but it dawns on you that you do not have the key!!! What will you do now?

Go back to the zoo. You don't need to deal with the mess stealing a car will bring you.

Go back to the zoo and stealthily take the key. Stealth is the key.

Bah, who needs cars to get around? Run away from the zoo, and ultimately your home.
