Plot
You meet your friend Sid at the mall and have to drag your little sister Joanie along. Your sister runs inside a magic shop and Sid winds up handcuffing his hands together inside the store. The shop keeper, who calls himself "The Magician" informs them that there is no key for the handcuffs and mysteriously disappears. You furiously drag Joannie out of the shop when you discover that Joannie was holding an old book of spells. Sid suggests that you use one of the spells to get the handcuffs off. If you chose that option, you wind up on stage during a magic show as The Magician prepares to throw knives at you, make evil rabbits come after you, put you inside a box and put swords inside, or sawing you in half. If you tell Sid that to not try any spells and go back to the clubhouse and try to use regular tools to get the cuffs off, three bullies from school take the book and The Magician forces you to get it back.... by making Joanie slowly disappear as leverage!
