Robby Ferber
Debut: Goosebumps Slappyworld #4: Please Do Not Feed the Weirdo!
A seemingly normal boy claiming to be caged at the carnival Jordan and his sister are attending by his abusive father, only to turn out to be a shapeshifting monster with a constant craving for food.
- The Bad Guy Wins: Mr. Ferber, the boss of the carnival, captures the wrong Jordan when Robby transforms into a duplicate of him, allowing him to have Jordan's life as he wished — though this may not last long considering what happens every time he eats.
- Bears Are Bad News: He's described as resembling a bear in his monster form.
- Big Eater: Constantly begging for food. You wouldn't want to give him any, though.
- Bitch in Sheep's Clothing: He wins Jordan and Karla's sympathy by pretending his father regularly locks him in a cage at the carnival as a laugh and begs them for food, only to then spew vomit and transform into a monster after eating the candy bar they offer him.
- Consummate Liar: Jordan notes what a good liar Robby is when the latter demands to meet his parents and then acts innocent in front of them.
- Super-Senses: He claims to have super hearing when Jordan and Kayla try to whisper around him.
- Voluntary Shapeshifting: He can shapeshift into anyone. In fact, he shapeshifts into Jordan's teacher when Jordan suspected another classmate of being Robby instead, and even shapeshifts into Jordan himself.
