The Grid is Greener on the Other Side of the Screen by Hi_Im_A_Penguin

Summary
“It felt like a joke at first. The person in the mirror looked exactly like the one he saw in all the posters and merchandise not too long ago. Spamton tried to rip off the assumed picture of Tenna facing him, only to realize he was grasping onto a smooth, cold surface. The Tenna on the other side wasn’t even smiling or posing like the others, instead he looked as distraught as the salesman was feeling right now.
Spamton raised his hand to feel his face, while the reflected CRT followed suit. His plastic puppet jaw was nowhere to be found, being replaced by a boxy matte chin and a glass surface where his face should be. He reached over to the top of his head, feeling not hair, but two thick antennas like the ones he sees ahead of him.
Spamton’s mechanical heart sank as the realization settled in. This wasn’t a dream; it felt too real to be one.
He had become his worst enemy.”
AKA: Spamtenna but it’s your typical body swap episode.

Heaven was finally in Spamton's grasp. He escaped the dark world's confines and became a lightner. He truly was free now, but in his pursuit of freedom, he realized one simple thing—that he never thought out what he would do with his newfound independence.

Summary
Spamton thought it was the end of the world when he saw a beacon of light pierce through the summit of Mount Ebott and soar into the sky, not knowing that he had born witness to the shattering of the ancient barrier that trapped monsterkind beneath the mountain.
Magic had begun to flow back into the world, and creatures he had believed only existed in fairy-tales suddenly began to settle down and live in Elysium city.
At first, he thought he could ignore it, but after his workplace adopts a monster integration program, and he is forced to look after his new coworker, he finds that his life is suddenly full of questions from an obnoxiously curious ant.

Summary
He swallowed hard, trembling but unable to tear his gaze away from the being before him. Fear still rooted him in place, but curiosity—foolish, human curiosity—kept his eyes fixed on the way the moonlight caught the monster’s fur, the faint curl of his antennae, the glint of sharp teeth in the dark.
It should have been pure terror. And yet… it wasn’t.
And that fact almost scared him more than the monster did.

Summary
To no one’s surprise, existing as a lowly Addison... followed by the live-fast BIG SHOT [Cungadero] lifestyle... taking an unwanted acid bath and being homeless (if you didn’t count the dumpster) and then BEATEN UP BY CHILDREN... none of this does a body any good. Particularly not when said body is sad and stunted, made of wood and fluff.
It also no longer looks great in a suit jacket, which is perhaps the biggest shame.
Or:
Hanging around Castle Town after his battle with the [Sponge]s, Spamton meets an old flame again, and has to reassess everything he thought he knew about his ruined body.

Summary
Somebody had opened a second dark fountain in the Dreemurr living room, and as much as Tenna had begged the lightners, Kris and their friends had to leave his show early to close the more threatening one first. He’s not entirely sure whether his deal with the Knight includes stopping the kids from closing any and all fountains, or just the one giving his own world form, but it’s certainly distressing to think he’s already ruined his last chance at a comeback. So, naturally, he follows after them.

CRTs are capable of rewinding and replaying. All Tenna has to do is get it right.
…Easier said than done, especially when it starts looking like Spamton’s phone caller might be more than just a business aficionado.

Summary
He brought his hand to the side of Spamton's face. He was tiny in his hold — his thumb ran from his forehead to his chin and his fingers easily wrapped around the back of his skull. "Please? Whatever you're afraid of—o-or you're worrying about, we can face it together! That's...that's what this means, right?"
“…yeah," he said quietly. "Yeah, it is, Ant." He looked to the side, froze once more, like he was waiting for something again. Whatever he was waiting for didn't seem to come, because Tenna felt the moment those tense strings were cut.
The stiff line of his shoulders softened, that wobbly smile on his mouth returned, and he leaned into Tenna's hand, his own coming to rest near Tenna's thumb knuckle.
"I will," he said after a beat. "As soon as the [[tell the papers!]] are signed, I will. I...I promise."

Instead of picking up the phone, Tenna chases after Spamton. Unfortunately, he's far too late to save his little mailman from his fate, and his own might just get tangled up in the strings.- Language:

Summary
Though perhaps, Spamton thought, they should be more careful to make sure it doesn't feel too uncanny behind the scenes. Perhaps they should hang a painting on the back of one of those big wooden set pieces. Perhaps they should dot colorful tissue boxes and plastic succulents on whatever surfaces of the studio were stationary.
After all, spaces that did not feel sufficiently human invited things that weren't.
