“Look out, everybody, things are about to get awesome!”
Jack-in-the-Box is one of Claptrap's internal representations of Handsome Jack in the Claptastic Voyage DLC from Borderlands: The Pre-Sequel. He is found in Subconscious. Like a Jack-in-the-Box toy, he starts as a box with a crank on one side - once turned three times, Jack's head will pop out. He is capable of hopping around in that state, and is obsessed with Claptrap's fears.
Jack-in-the-Box provides the Vault Hunters with a single mission, The Sum of Some Fears, in which he expresses a desire to find out what Claptrap's most afraid of, and is excited to delve deeper into Claptrap's subconscious to find out. Ultimately, he becomes disappointed with the mundanity of Claptrap's deepest fears, and attempts to hijack the scenario by attacking with Insecurity forces, but is ultimately driven off.
