It's worth mentioning that the product checks your system to see if you’ve downloaded a previous title in the Too Ghoul For School series. If you have, additional parts of the bonus story will be unlocked.

Also, each product has DSi Camera support. You can add a photo of your friends and family to an image template (rat/cockroach/zombie/spider – one per book) and save it to the system album. It’s a simple feature but I think children will enjoy it.
