It was a typical Sunday morning in the Watterson family. Anais was watching Daisy the Donkey, Nicole was washing dishes, and Richard was sleeping on the couch.
However, Gumball and Darwin were still in their bedroom.
"Darwin? Are you as bored as I am?" asked Gumball.
"Yeah, dude. But Anais and Dad are hogging the couch, and Mom hates it when we get snacks out of the kitchen when she washes dishes. So there's not much to do." he replied.
"We could go for a walk," Gumball suggested.
"Fine." said Darwin. He sighed. "I wish we had an iPhone.."
Gumball changed out of his pajamas and into their usual outfits. Darwin didn't change at all, since he never wore pants anyway.
They walked around the neighborhood briefly, passing about 20 houses before they turned back to their house.
They listlessly walked back to their bedroom to figure out what to do next.
"Gumball, do you feel any different?" Darwin asked.
"Nope." he replied. "You?"
"No." he said, swinging his legs while he sat on top of his fish bowl. He accidentally kicked open a drawer, and inside it was a bottle full of a strange-smelling liquid, labeled 'LSD'. Darwin smiled sheepishly.
"Dude, what is that?" Gumball asked, staring at the bottle.
Darwin smirked. "Something that might cure your boredom. Try it." Then, Darwin took a tiny piece of blotter paper, and poured some acid on two pieces , and they popped one into each of their mouths.
Gumball's pupils widened, his heartbeat was now twice as fast, and he felt slightly dizzy.
He saw the colors in his room swirl and merge. He saw amazing, bright colors jump and fly right before his eyes, seeming almost like a light show.
Then he looked over to Darwin, who now looked like a blob of purple, blue, and green, with now only a bit of his original orange skin, in Gumball's distorted point of view.
To Darwin, Gumball looked like a rainbow-colored mess.
Everything was different. It was like bright colors had taken over, and repopulated. Gumball had never seen anything like it.
"Dude! Let's go for a walk..." said Darwin.
"I...can...see...sounds..." said Gumball, a bit dazed.
"Yeah, that's how I've felt when I first took it. You get used to it, though." Darwin said, like he had taken acid for a long time. He sounded perfectly fine, like nothing had changed.
"Ha-ave...you...been...hoar-hoarding...drugs...?" Gumball said in distorted speech. He was staggering around, obviously dizzy.
"...Mmmaybe," Darwin bragged, spreading a grin across his face. He turned his grin into a scowl, then grabbed Gumball by the shoulders. "But if you say ANYTHING to Mom, I will DISOWN you." he snapped.
"Y-yeah...sure...'kay..." he agreed, not really hearing what Darwin had said.
They went for another walk. Darwin had casually walked around the neighborhood, like last time they had gone, Gumball was throwing rocks at cars, thinking he was throwing cupcakes to Rainbow Bunchies.
Darwin was seconds away from noticing Gumball's absence. Darwin pulled Gumball away before he hit another car.
"What the hell are you doing? You're gonna get the police called!" Darwin said, annoyed.
They went back to their house. By the time they went back to the kitchen, the acid effect had worn off.
Gumball was now an LSD addict, and collected his own stash of LSD bottles that he combined with Darwin's.
