Scooby-Doo 2: Monsters Unleashed review:
For those people who've seen the movie, you can unlock a secret ending when you complete the game by entering the password given out in the movie (I assume in the end credits but can't confirm this.)All in all, if you've got children who are mad about Scooby Doo, have a GameBoy Advance and have been 'good' or have a birthday coming, Scooby Doois worth checking out.
