Winnie the Pooh and his friends (along with Ash, Simba, SpongeBob, Danny, Sawyer, and their friends) meet Danny and Sawyer's old friend Billy and his new pet mogwai Gizmo as they learn three rules about how to take care of a mogwai:
1. Keep it away from the bright light (including the sunlight).
2. Don't get it wet.
3. Don't fed it after midnight.
But they didn't listen to the rules because the new Mogwais soon transform into the hideous Monsters called the Gremlins and begin to create chaos into the town. And now it's up to Pooh, Ash, Simba, Danny, and their friends to stop those Gremlins or everything will be a hideous nightmare.
