Tell a movieclip to go to a frame

Hey:) does anyone know how to make a movieclip go to a frame using as3?

I’m making a virtual pet game, I want the user to be able to choose from three possible pets at the start…

Once they click on the pet that they want to ‘adopt’ I want the pet movieclip to be used from then on in my game, but I can’t even figure out how to get pet_mc to go to the frame where the game would begin?

Do you use addChild or something?
