Plot

Depending on whether you choose to sneak out the window or hide in the attic, you will face either aliens, werewolves, or secret agents.

Trivia

 * Although werewolves have appeared in Give Yourself Goosebumps before, this is actually the first and only book where the idea of silver items being a threat to them is introduced. This is usually an accepted fact about werewolves.
