Zach and Champ broke into R.L Stine's and Hannah's house in order to 'save' Hannah, but they did not. Instead they found books, Goosebumps books. They opened one, one with The Abominable Snowman, and also Night Of The Living Dummy. They only knew they opened the book with The Abominable Snowman. So they had to fight him. Eventually Hannah came to the rescue, but it didn't turn out great.. R.L Stine had to save them and he was MAD. But he didn't know another book opened..
