Author's Note: Hey, happy reverse birthday present... thing! It's my birthday today so I was like "Screw homework, I'm gonna post the first part of the challenge!" Yeah, it's kinda weird, and the quote has nothing to do with it. I just really love Muppet Treasure Island.

This is sort of an excerpt from a story series idea I have. I'm unsure if it'll ever be complete enough to put onto fanfiction though.

"Sailing for adventure on the big blue wet thing!"

-Fozzie Bear, Muppet Treasure Island

"Any sign of it yet, Brain Boy?"

"For the last time, Cleft, I changed my name to Brain Blaster!" The hero-in-training shouted over the intercom to his three class-mates who were waiting back at the super-school while their comrade explored in the single-man submarine.

"Asking me every five minutes is not going to make finding the device any easier!" Brain Blaster continued to yell.

"Ok, ok, sheesh!" Cleft replied, holding the microphone and watching the feed from the sub's outboard cameras.

A second boy was sitting in the corner with a very forlorn look on his face. "Ough, my dad is gonna KILL me!"

"Don't worry Tigre, we'll find it before anyone notices it's gone." The third boy, who also happened to be the oldest, assured his friend. "Otherwise, we'll all be expelled."

"Heh, not you Phantom." Cleft told him, "You're the top student at school and already recognized as an international hero."

"Yeah, I don't think that's going to excuse me from letting loose a super villain and then losing his most world-threatening weapon." Phantom replied dryly.

"Guys, I can hear every word you're saying." Brain Blaster informed them over the radio, "And it's really making it hard for me to concen—"

He paused in shock.

"Did you find it?" The others asked excitedly.

The sub pilot shook his head slowly in awe before remembering they couldn't see him.

"I found something else… it's… unbelievable."

The feed from the outboard camera shifted as Brain Blaster fumbled with the controls.

Back on land, the screen displayed a strange under-water horizon, littered with huge old pipes and boat engines; things that could easily be scraps from old shipwrecks. The strange thing was that they were way too clean, and arranged neatly, almost like a city skyline. In fact, were those… windows on the sides of them?

"Is that…?" Phantom began to ask.

"An under-water city, yes." Brain Blaster finished, bewildered. He gazed in wonder as he passed the first building on the outskirts of town. A house big enough for him to enter, shaped like a giant pineapple. A pineapple under the sea.

Yeah, this is something that's always bothered me about Spongebob when he interacts with the other Nicktoons. In the show, it's usually pretty clear that he's the size of a regular table sponge and he just lives in a small-scale world (Like in Frankendoodle and the Movie, for example) But when he's around the other Nicktoons, suddenly he's the same size and Jimmy! How does that work? So, to make things easy, I just went with the large size option.
