This is about a boy named Larry. He and his friends find some Insta-Tan lotion and they rub it all over themselves but nothing happens until Larry starts growing thick, black, ugly hair that keeps growing back even after he shaves it off. Then his friend Manny moves without saying goodbye and next his friend Lily. He found a stray dog that had a gold coin around its neck like Lily did and a green eye and a blue eye. He thinks it's Lily but then it runs away. Then he finally is able to show his parents the hair that's growing after a concert and they tell him that he's really a dog. His doctor found a serum that can turn dogs into human children for a little while. Larry then finds Lily and Manny as dogs. The story ends where his former parents bring home a baby with big yellow eyes named Jasper, which was the name of their cat.
I wonder what would happen if R.L. Stine continued this into a next book. I don't think he will though. If he did then eventually Jasper would have to find out that she's a cat and she would meet Larry. That would be very strange.
