Author's note: sorry about the wait. I just moved into my dorm recently and haven't had the time to sit down and write lately.
Throughout the next few weeks, Sandy and Sheldon grew closer together, becoming nearly inseperable. It wasn't uncommon for the average Bikini Bottom denizen to see the land mammal carry the coepopod around in the pocket of her underwater suit. Mr. Krabs gritted his teeth and just waited for the opportune moment to launch his attack against Plankton, who was coming closer and closer to the Krabby Patty secret formula, eating so many procured by Sandy. Squidward also gritted his teeth, hoping that Sandy would finally come to her senses.
It was a dark and stormy night when Mr. Krabs put his evil plan into action. He kicked open the door of the Chum Bucket.
"Hello, Sheldon."
Plankton glared. "Eugene. What are you doing here?"
"I been noticing you've been hanging around that little squirrel."
"What's it to ya?"
"Well, I'm sure you'd like to hold her. Or kiss her. Or make love to her."
Plankton looked Mr. Krabs in the eyes. Sure, he wanted to do all these things, but he couldn't let Mr. Krabs see that. "Your point?"
"I hear tell of a Sea Witch who lives on the outskirts of Rock Bottom. They say that she'll grant ye one wish, and this wish can be fer anything in the world. She could turn ye into a squirrel so's you could be with yer girlfriend."
Plankton felt this sounded too good to be true. "What's in it for you to tell me this?"
"I want Sandy to be happy."
"Since when has Sandy's personal happiness been any of your concern, Eugene?"
"Since she's become a VIP customer at the Krusty Krab."
"I don't care about your fairy stories, Krabs. Sandy and I are perfectly happy on our own."
"Suit yerself," Krabs said, leaving. "I'm leavin' a map by the door if yeh change your mind."
Plankton waited a full fifteen minutes until his curiosity got the better of him. "I guess it couldn't hurt. I'm not doing anything tomorrow."
The next morning found Plankton outside the Sea Witch's cave. "Hello?" He ventured into its gaping maw. "Anybody home?"
A Ghastly Greenish Bearded Woman (heretoafter abbreviated as "GGBW") suddenly appeared. "Come in, Sheldon."
"How do you know my name?"
"The Sea Witch knows all, young man."
"Then you know why I'm here."
"You want to be able to better suit your girlfriend."
"And world domination. Don't forget the world domination."
"I can only grant you one wish, my son. Choose: love or power."
Immidiately, Plankton said "Power... no Love. Love. Final Answer: Love."
The GGBW handed him a potion. "This elixir, when drunk, will turn you into a squirrel until midnight."
"Hot damn!" He was about to drink, when he paused. "Wait, I won't be able to breathe underwater."
"A gilled squirrel"
Not finding anything wrong with that logic, Plankton drank the potion deep, and in a poof bubble reminiscent of the Fairly OddParents, Plankton became Sheldon the gilled squirrel.
"You might want these," the Sea Witch said, handing him a pair of board shorts. "You're anatomically correct."
"Thank you, madame Sea Witch!" Sheldon yelled and ran to Sandy's treedome. He knocked on the door.
Sandy opened the door. "Hello?"
"Hello, Sandy."
"Sheldon?"
He grabbed her by the waist and kissed her for the first time. He picked her up, closed the door, and carried her up to her bedroom.
