Spongebob 10pants

SpongeBob 10pants is a spin-off of the original series of SpongeBob SquarePants crossed over with Cartoonnetwork's Ben 10, created by sponge45. SpongeBob 10pants is about a young 10 year old SpongeBob SquarePants who was on a road trip with his grandpa Larry (who is grandpa SquarePants in the regular series) and his annoying cousin Avery (who has no relation to any SpongeBob SquarePants characters) when he found a special watch called the omnitrix, that turns him into aliens that he uses to fight evil.

Series Plot
On the last day of school, SpongeBob SquarePants was picked up by his Grandpa Larry, so they can start on their summer road trip. Once they get to the their first stop in the woods SpongeBob takes a walk. A giant meteor crashes in the  woods. It turns out to be a spherical container, that when opened a watch appears. SpongeBob tries to grab it, but it jumps on his wrist. He tries to get it off but, it's stuck. Since then he uses the watch to save Earth from any threat it faces, with the help of his Grandpa Larry and cousin Avery.
