A/N: The beginning is very similar to an episode, but the story works off of it.

Disclaimer: I do not own Spongebob Squarepants or any of the related characters.

"Nuh-uh! Land creatures are far more superior," argues Sandy Cheeks. "What's so important about what you sea critters can do?"

"Well, Sandy, for your information, what we 'sea critters' can do is very important. We can breath without a helmet!" Spongebob Squarepants answered.

Spongebob and Sandy stood in the middle of the legendary fast food restaurant, the Krusty Krab, home of the Krabby Patty. They were debating whether sea creatures or land creatures were better. We all know that they are both equally great, but Spongebob and Sandy beg to differ.

"Psh! This old thing?" Sandy said, pointing to her air helmet. "I don't need this!" And with that, Sandy removed her helmet.

10 seconds passed.

"You know, you're gonna need to breath any moment now," Spongebob said, with a widening- and might I add, satisfactory- grin on his face.

Sandy tried to ignore Spongebob, but it felt like her lungs were about to burst. She waited as long as she could, but couldn't go very long. She grabbed her helmet and stuffed it back on her head.

Spongebob laughed his famous laugh as Sandy took several deep breaths, trying to refill her lungs.

"It's not funny!" Sandy shouted.

Soon everyone in the whole restaurant burst into laughter, staring and pointing and then laughing some more. She heard cries of "Ha! Dumb land creature! Can't even breath underwater!", and "Stupid air-breather…"

"Fine! I bet that you can't go above water for five mintues!" Sandy said.

"Ha! Piece of cake!" Spongebob replied.

"Okay! Let's go then!" Sandy said, and led Spongebob out the restaurant.

When Sandy and Spongebob reached the part of Bikini Bottom that goes uphill onto land, Spongebob looked up nervously, almost seeming as though he was going to back out and let Sandy win the bet. Sandy stood next to him with her thumb hovering above the 'start' button on her stopwatch.

No, I can't let her win! Spongebob thought. He squared his shoulders, puffed out his chest, and ran up the hill, shouting "Sea creatures rule!!"

He popped up out of the water with a splash, but was immediately smashed by a wave. He got twirled upside down, backwards and then upside down once more.

Woooo!! Yeah! This is great! Spongebob thought, rather optimistically. This is so easy! I'll win this bet in no time!

And just as Spongebob was beginning to enjoy his ride, the sensation stopped, as Spongebob washed up ashore.

Just as this was happening, a little boy was scooping up a large bucket of wet sand when he saw Spongebob. To the boy, Spongebob appeared as, well, just a sponge.

"Oh cool!" He exclaimed.

He picked it up and rushed over to where his mom sat relaxing in a beach chair reading a magazine.

"Hey mom! Look what I found in the water! A yellow sponge! Cool, ain't it? Can I keep it?" The boy said excitedly to his mother.

His mom peered at him over the top of her sunglasses. "Jimmy, what's so special about a yellow sponge? And who knows where that's been! And no, you can't keep it!" she added on at the end, seeing her son about to say something, and she knew exactly what it was.

Jimmy walked away sadly holding his bucket. He dropped his bucket next to his sand castle building site, and walked slowly and sadly towards the water to put back the sponge. He looked at it longingly, and then glanced back at his mom. She was absorbed in her magazine again, completely oblivious to everything going on around.

Jimmy grinned. He had a plan. He was determined to have this yellow sponge, despite what his mom says. He squeezed the sponge tightly in his hand and hid it in the pocket of his swimming trunks.

Woah, there! This is a little bit more than I expected! Spongebob thought. And now I'm stuck in this enclosed… thing! He struggled around in Jimmy's pocket, but got absolutely nowhere.

Meanwhile, Sandy stood at the foot of the hill, keeping an eye on the top of the water to see of any signs of Spongebob giving up and one on the stopwatch.

Four and a half minutes… pretty good. Maybe he's tough enough to be live water and on land, Sandy thought. Well, there's still time for me to win.

On land, Jimmy trudged up the sand to where his mom still sat, and slipped Spongebob into his beach bag. He glanced nervously at his mom, sitting right next to him. She still didn't seem to notice.

Yes! Success! Jimmy thought and pumped his arm in the air.

Spongebob lay in the bag, wondering, Where am I? What's going on here? I need to get out!!

He twisted and turned in the bag, but once again, made no progress.

This is no good… how am I going to get out? Why is this happening?? I-… and then Spongebob realized who was doing all of this to him. Well, gee, I knew she wanted to win the bet, but she didn't have to go this far!

"Okay, Sandy! You can come out now! I've learned my lesson! It's all good!" Spongebob called out, expecting to be brought out of the bag and put back in the ocean.

There was no answer; just the shouting and talking of people, the crashing of waves, and the nearly non-existent sound of people turning the pages of their magazines.

Where is Sandy?
