Super Diaper Baby 2
Dr. Dilbert Dinkle first appears in Super Diaper Baby 2: The Invasion of the Potty Snatchers. He and his sidekick, a talking tabby cat named Petey, are seen sneaking an invention to Jim's Bank. Dr. Dinkle starts explaining to Petey that his new device can turn any solid material into water by rearranging molecules, when he interrupts his master to tell him that he has bad breath. Dr. Dinkle ignores his remark and shoots the wall of the bank, turning it into liquid water. Petey, however, gets bored and hides behind a bush, so Dilbert gives him the job as the lookout. While Dr. Dinkle is measuring the vault before he can use the invention to turn the vault into water, Petey accidentally sets off the lever of the invention at Dr. Dinkle and Dr. Dinkle is turned into water. Dr. Dinkle berates Petey for his clumsiness and Petey accidentally breaks the invention, meaning that Dr. Dinkle is now permanently made out of water, but Dr. Dinkle actually likes being made out of water when he is able to steal the money by turning into a puddle. Petey complains that all the water in the city is turned off and Dr. Dinkle doesn't care and goes to sleep in his puddle form, so Petey manages to get revenge on Dr. Dinkle by drinking him and when Dr. Dinkle wants to get out of Petey's body, Petey heads to his liter box and Dr. Dinkle becomes shocked and horrified that he has been turned into pee.
