Run away from the giant creature

From Create Your Own Story

You start to run away from the creature, and the creature runs after you. You hear footsteps behind you, but they sound like human footsteps. You look back. Alex is holding the creature, and it's a DOG! Alex laughs again. You charge at him with anger. He backs off, "I was just joking!" You are still angry. "Why did you run away from the park?" "To scare you. I'm angry because you annoyed me in a parallel universe." You stare at him cluelessly.

Take Alex to your parents Ask how he got the dog Ask how he got so dirty
