The story behind this is Mario and Luigi go through a warp pipe that they think will lead them straight to Bowser's Castle because he has Peach captive again, but they end up in the undersea city of Bikini Bottom, where they meet the ever-popular SpongeBob SquarePants and his bumbling buddy Patrick Star.
Mario: Hello, talking sponge and starfish!
SpongeBob: Hi new friends!
Luigi: EEK! A live sponge and a starfish?!?! Is this a dream?!?!
Patrick: Are they mermaids?
