"I mean, I could go with something small, like changing your hair color, but what's the fun in that?"
"Why not? I think I'd look great blonde."
You roll your eyes, "Sure, Jonas. Let's see here. Do you like chocolate or fruit more?"
"Chocolate. Why do you ask?"
"No reason." You type C to open up the settings. You scroll down and uncheck box limiting changes to only organic life forms, which unlocks further settings. You type in MUFFIN in the DESTINATION field , then other settings automatically shift in the program. You go through, changing a few more settings (ADD CHOCOLATE CHIPS). "OK, ready, Jonas?"
"I'm not if I like the way you're asking th-"
You activate the device and Jonas lights up, his features obscured, and he quickly starts to condense, his limbs and features pulling in, his details smoothing out, until eventually the process completes and light fades, revealing a muffin where Jonas has been sitting a moment before.
"Oh wow. It worked! Hey, Jonas, how do you feel?"
The muffin just sits there, not responding.
"Wait a second, let me check this." You flick on a speaker and then Jonas's voice starts coming through the speakers.
"-smells like pastries? Dude? Why can't I move?"
"Good, the telepathy speaker is working. Guess I forgot to leave your voice on. Must have turned off by default to match your form."
"My form? What form?"
"Let me show you."
You pick up the muffin and walk over to a wall mirror.
Through the speaker you hear Jonas say "How come I can see you holding a muffin? W-Wait...y-you...w-what...did you turn me into a muffin?!"
"Yep! And a pretty darn tasty looking muffin at that. Complete with chocolate chips."
"Dude! That's so damn weird! You can't just turn me into food."
"I just did, actually."
"You know what I mean. Turn me back!"
You admire the muffin, impressed that there doesn't seem to be any sign that the muffin was your friend. The device was really darn impressive. You gave it a curious sniff.
"Stop that! Are you listening to me? Being like this makes me feel really darn vulnerable."
You shake yourself. For a moment there, you'd forgotten that he was your friend and just a mere muffin. "Sorry, ur, well, the greater the shift, the longer it takes for the device to recharge. Don't wanna risk making reality snap or the device to explore or something. Especially when just testing it."
"Wait, so how long will I be stuck like this?!"
"Just like twenty four hours."
Jonas's voice gives some estranged sounds for a bit before eventually giving a resigned sigh. "...I guess I'll just have to deal with this. Just promise next time you use the device you turn me into something is cool. And don't get any funny ideas about eating me."
"Sure thing, dude. So anything you wanna do in the meantime? Have breakfast, perhaps?" You make a show of licking your lips, which makes Jonas growl through the speaker.
