Do you think that somethng bad will happen to Slappy in "I am Slappy's Evil Twin" or maybe a cameo from Wally??????

Because judging from the cover, Slappy actually looks terrified of Snappy. Could this also mean that Snappy could betray Slappy or actually hurt him?????? And, could you expect a small cameo from Wally?????? Like he could stop Snappy from harming Slappy. Or he could take part in a twist ending, maybe the main character might have stopped Slappy and Snappy and his father brings home Wally and bad things start happening again??????? Man, there could be so many theories on this by the time the book's release. What do you think?????? Comment down below :) :) :) :) :) :) - Slappy'sGirlfriend2598.
