Ace Ventura Jr.: Pet Detective

Ace Ventura Jr. is the son of eccentric 'pet detective' Ace Ventura, who had disappeared when he was a baby, and is attempting to follow in his footsteps, much to the chagrin of his mother, Melissa, who repeatedly tries to dissuade him from doing so. Currently, he is attempting to uncover who is behind a series of pet thefts occurring at his school, including a koi fish belonging to a girl named Laura, whom Ace Jr. has a crush on. Ace Jr. regularly relies on science nerd A-Plus (who has an advanced lab in his locker) to provide the forensics work for him and, much like his father, his work is openly mocked by the student body.

When Ting Tang, a baby panda that has recently arrived at the Miami Zoo, is stolen, Melissa, who was in charge of setting up a pen for it and its mother, is blamed for the theft and subsequently arrested. As both of her parents are out of town for a vacation, Melissa reluctantly invites Ace Jr.'s paternal grandfather, Rex Ventura, to look after him, and he immediately begins properly training his grandson in the family business so he can clear his mother's name. At the trial, Ace Jr. successfully proves that the footprints found in Ting Tang's pen could not have been made by Melissa, but Russell Hollander, a park ranger seeking fame from the case, has the evidence dismissed and she's ultimately sentenced.

Despite Melissa finally accepting that her son is who he is and revealing what happened to his father (Ace had disappeared over the Bermuda Triangle while escorting several geese south and is presumed dead), a despondent Ace Jr. decides to abandon pet detection and be a normal kid like she wanted, but a pep talk from Rex restores his confidence. Resolving to find Ting Tang's real kidnapper, Ace Jr. (now sporting his father's style and mannerisms), A-Plus, and Laura discover that the panda was actually the latest in a string of thefts involving high-profile animals (Princess the lapdog, Freedom the Hawk and Calypso the Magic Horse). After being unable to prevent Tabby the tabby cat from being taken, the group confronts Dr. Sickinger, whom they saw at the meet and greet Tabby was at and has a website called PandaHub. However, the somewhat insane scientist is ultimately proven innocent as the website is full of pictures of disgusting and unattractive animals.

Continuing to dig around, the group (now including Sickinger) discover that there has been unusual activity at the home of Quentin Pennington Sr., whose son Quentin Jr. is set to hold an extravagant birthday party there soon. Arriving as Laura's plus one, Ace Jr. finds evidence that Quentin Sr. has stolen the animals under the belief that he deserved them more than anyone else. When Hollander refuses to acknowledge the evidence, Ace Jr., with a distraction from A-Plus and Sickinger, uses a recording of Ting Tang's mother to locate the panda cub and the other animals, allowing the authorities to arrest Quentin Sr. and forcing Hollander to leave in disgrace. When Quentin Jr. strangely leaves the area, Ace Jr., after an offhanded comment from Laura, and the rest of the student body present discovered that he was responsible for the school pet thefts, having discovered his father's illicit activities and wanting to make him proud. When he attempts to feed Laura's koi fish to the school alligator, Quentin Jr. is stopped by Ace Jr. and Rex's dog (whom Ace Jr. had assumed was dead) and is arrested as well. Melissa is released from jail and Ace Jr. is rewarded for his heroics.
