Gary

"Meow?" Gary said when Spongebob got home from work.

"Oh, right, your dinner," Spongebob said. "Hilda!" A woman in a maid outfit ran into the room.

"At your service, Mr. Squarepants!" she said brightly.

"Hilda, would you kindly feed Gary? Then you may go home. Thank you." Hilda curtsied and walked back into the kitchen.

"Come on, Gary!" she called. Gary slithered in.

"Meow?" By this he meant, "Who are you, and why is the kitchen so big and fancy?" Hilda just giggled.

"You are sooo cute!" she said, bending down to pat him on his shell. Normally Gary would've purred, but he didn't like strangers touching him. Of course, when the lady put the food bowl on the floor, he instantly loved her.

Later that night Gary roamed the pineapple as usual. But the for the first time since he first arrived, he got lost. This can't be my home, he thought. The pineapple was never this big! He slid into what he thought was Spongebob's bedroom, but turned out to be the third bathroom he had seen that night. This one was all blue, with a little towl beside the miniature bathtub that read Gary in fancy, curly letters. The sink was Gary height, too, and instead of a toilet there was a jewel-encrusted litterbox. Since when have I had my own bathroom? Gary was very confused. He was tired, too. Since he couldn't find the comfort of Spongebob's room, he curled up on his personal towl and slept there all night.

(Note: Yeah, another short one! In case you haven't figured it out, Gary wasn't affected by the orb, because he had found an underground tunnel and was exploring it. The thick earth above him protected him from the flash. Everyone else has turned into their opposite selves.)
