It’s the Washing Machine Monster, Tumbles!! I made this fella only a few months ago, but I think I was delirious on sick meds I have no idea what I was doing, so he’s kinda needed an overhaul since day one
Tumbles was some sorta marsupial monster and an assistant to a mad scientist, ‘cause he needed the money but there was a disaster and Tumbles was caught in the middle of it.. The scientist planned to save him by ’upgrading’ him into an ‘cybernetic killing machine’, but all they had on hand was an old washing machine and scrap metal (and Tumbles is not like that anyways, he’s a big docile bby) :v Tumbles still has his own heart, lungs, brain (and possibly liver and kidneys) but his voice box, most of his limbs and most of his digestive system had been lost, and replaced with the mechanic parts you see, (though his voice box wasn’t, so he can’t talk but communicates with body language and various beeps and noises)
The scientist he worked with has long since passed, Tumbles was ‘adopted’ by a nice lady who owns a laundromat and now he wanders around town, washing clothes and things for folks who need it :3c
