Nutty

(Profile still a bit of a WIP!)

Nutty is an advanced robotic 3D printer, built to handle high-speed precise printing and model generation from visual input from his camera eyes.
Utilizing AI, he's able to make almost any sort of print entirely on his own without human guidance, using his small arms to pick up finished prints or attach pieces manually.
Normally, this would be an amazing piece of technology, except for one small problem:

Nutty is absolutely insane.

He was never originally intended to be a squirrel. His original form looked a lot like the endoskeleton version; just a basic robot built for it's task.
However, one day when placed by a window by it's creator to gather nature models for a project, a live squirrel came into view of the printer.
Note that his AI isn't exactly the most stable at this point. The AI program that got input into the 3D printer originally wasn't compatible with the printer itself, so janky workarounds had to be programmed in.
This made the AI unstable and prone to glitching, yet it was still functional. After that squirrel came into vision and the printer scanned it, however, something broke in the code.
The error caused the printer to act absolutely haywire, becoming COMPLETELY obsessed with squirrels from that point on. Its personality erroded into a "crazy squirrel" stereotype.
After his creator noticed this (and was shocked the printer was still functioning), he added some animatronic modifications to the printer head, giving it a tiny fur suit.
From this day forward, the printer named itself "Nutty", fully believing itself to be a real squirrel.

Nutty is extremely chaotic and unpredictable, constantly going into ravings and nonstop conversations about anything squirrel related.
It's not uncommon for him to talk for hours about squirrels, never needing to catch his breath.
He's also extremely glitchy and prone to errors and crashes, usually requiring a reboot from his creator during particularly insane ramblings.
He is always on the move, waving around his arms, making tons of faces, and zipping along his printer rail all the time while talking.
This wears out his motors very quickly, and it's not uncommon to need repairs after a week or so. (To the ire of his creator)
However, his insane personality has thankfully not affected his printing ability! He is still an extremely advanced 3D printer, properly printing any object shown to him with high accuracy.
What exactly he prints though, is another thing. If you don't specify exactly what you want printed, it's most likely he will add his own squirrel-themed touches to it
Needed a hook to hang your keys on? Squirrel tail hook! A car with spinning wheels? The wheels are acorns!
Thankfully if you catch Nutty in a relatively sane mood and be specific with what you want, or provide an image for him to work off of, the prints will turn out fine.
But if you ask for a print while he’s in a particularly insane mood, he may just ignore the request entirely and print out whatever his scrambled little AI manages to generate, which can be quite complex in terms of design.
Nutty has a particularly amusing way of printing; he opens his mouth to expose the printing nozzle inside, looking down in order to print it out. He also tends to make "bleeeegh" sounds while doing so.

Nutty takes great pride in his prints, and always gets very happy and excited whenever a print turns out the way he wanted.
Despite his insanity and glitchiness, his prints have been used in major projects with satisfactory results, such as Bubble's inner skeleton being 3D printed by him.
On the rare occasions a print manages to fail, though, he becomes absolutely devastated, shrieking in agony over all his work gone to waste.
His normally eager and crazy mood will become sullen and depressed, requiring someone to cheer him up before he gets the confidence to print again.
Thankfully this is very easy to do; just start talking about squirrel related topics with him. He will become his usual insane self again very quickly.
He also gets very upset if a print is taken from him as he's working on it, and will refuse to print for you again until you give it back and apologize.
Nutty becomes super uneasy whenever he runs out of printer filament, constantly begging for a refill as soon as possible.
