Maybe Spongebob and Patrick end up in Equestria. They meet Rainbow Dash, who is initially skeptical of these strange new creatures. But then they challenge Rainbow Dash to a race. Spongebob and Patrick use their unique underwater skills in a creative way on land to keep up with Rainbow Dash. As they race, they accidentally stumble upon a hidden cave that holds an ancient magic. The ponies and the Spongebob gang have to work together to make sure this magic doesn't fall into the wrong hands.
One possible plot could be that Spongebob somehow gets transported to Equestria. He befriends Pinkie Pie first because of their similar energetic natures. They start having a party together, and Pinkie Pie shows Spongebob around Ponyville. Then, they might encounter a problem like a mysterious spell that's making all the ponies sad. Spongebob, with his positive attitude, tries to help the ponies cheer up and along the way, he meets Twilight Sparkle who teams up with him to find a way to break the spell.
