The PET in Leave It To PET is a plastic bottle, not a device that houses a Net Navi inside.
Or the old Commodore computer.
Left 4 Dead is not a story about a person who, after the four people closest to him and absolutely no one else in his hometown are killed, goes on a epic quest to hunt down the mysterious perpetrators of the killings and discover the reason for the attack.
It's not a fourth installment in Left series entitled "Dead".
Nor is the ship a Nissan pickup (or built to look like one).
Mad Jack The Pirate episode "The Treasure Of The Headless, Left-Handed, Peatmoss Salesman" is not about the treasure or the salesman but rather about Mad Jack having to renew his pirate license. Mad Jack just happened to be looking for that treasure when the authorities caught him.
The Princess and the Frog does feature a princess and a frog.. but never at the same moment. Tiana is never a princess while interacting with Frog!Naveen, and once she is, she and Naveen have both turned back into humans.
