User blog comment:Slappy'sGirlfriend2598/Do you think that somethng bad will happen to Slappy in "I am Slappy's Evil Twin" or maybe a cameo from Wally??????/@comment-27855893-20170316214131

My theory is that Mr. Wood appears and it turns out that the real purpose of Snappy is to betray Slappy and try to kill him to take the place of the "main Goosebumps villain." Mr. Wood, despite how evil he is, decides to help Slappy. Slappy finally, just by this time, decides to go to the good side and joins with Mr. Wood to kill Snappy.

But something does not go well and Snappy comes to kill Slappy, Mr. Wood with nothing to do decides to call the rest of the Goosebumps dummies (Mary Ellen and Rocky), between all come to beat Snappy and kill him. However, there is nothing to do with Slappy anymore ...

Everyone realizes that even though Slappy has died, his soul would be transferred to another dummy, so that his soul is transferred to Snappy and from there Slappy revives ...

But as a twist ending, it turns out that a bit of Snappy has still been left alive, so he would have some control over Slappy.
