Your naked friend is obscured by a flash of bright light.
When the light clears, there is a minotaur standing there.
You rub your eyes, the minotaur is still standing there, a huge creature with a bull head, complete with intimidating horns, a nose ring hanging from its snout, black fur covering its entire body, massive hooves clopping against the sidewalk. The only clothing is a faded crimson loincloth around its waist.
The minotaur rubs its hoof-tipped hands to its face, rubbing their eyes, then speaks. The voice sounds a bit like Keith, though deeper and with a slight mooing bellow underneath. "Whoa. I feel really weird. What happened?"
"K-Keith?"
"Yeah. What's going on?" The minotaur gives you a curious look. "Huh. Did you get smaller?"
"N-No, but...urm...you might have g-gotten bigger." You can't keep the stammer from your voice, your mind stuggling to parse the new form of your friend. The keys couldn't have done this, right? You step forward, reach up slowly, and poke at the minotaur's nose ring, the silver surface fogged up whenever the bull creature exhales.
The minotaur stares cross-eyed at you as you do this, then lightly slaps your hand away from the nose ring. "Hey! What are you..." He stops as he comes in contact with the nose ring, feeling it, pulling at it a little, giving a small confused "moo". He then looks down at himself, his arms, his legs, his loincloth, then gives a louder confused mooing bellow. "Wh-What's going on? What did you do to me?" He pushes the loincloth to the side to check underneath, then bellows again, clutching his groin. "What's going on?"
You steps back, a little scared of the increasingly agitated mythological creature. "Whoa. Settle down! I don't know! I just...pressed the button on these keys and...well...?" You make a helpless gesture and shrug.
"Well, fix this! Now. Or find me a maze to work on. I really want to do some mazes. Mazes are cool." The minotaur seems distracted by the thought of mazes, before shaking his head, his ears twitching. "Whoa. That's...this sort of thing doesn't just happen! Fix it!"
You fumble with the keys and ready yourself to hit the button.
