Size & Weight

Muck weighs about ten tons in all forms.
In vehicle form, he's 27' long from the tip of his lowered blade to the back of his dumper. She's 15' tall to the top of her dumper or 14' to her cab roof.
In middle form, he's 16' long from nose to rump and 14' tall, including his horns.
In biped form, she's 23' tall, including her horns.

Physical Limits

Muck's top speed in both vehicle and biped form is just about 35 mph, though he can't reach that speed often. In middle form, she can easily charge at speeds over 45 mph.
Muck's made for hauling heavy loads. He can haul just under eight tons when using both his dump bed and his blade. She can carry about the same weight in both other forms.

Other Physical Notes

The powerful hydraulic systems and sturdy chassis that allow Muck to lift and carry heavy loads in vehicle form are repurposed in his other forms. Though she's still not very dextrous, she has an incredibly strong back in her middle and biped forms - she can still lift about eight tons total through all forms.

Muck is a very vibrant character. He's playful, energetic, and kind-hearted. She has a lot of big feelings and he has no problem communicating them with her peers. He's also rather cheeky, impulsive, and unpredictable. She tends to leap before he looks, making her fairly clumsy, but she's quick to pick up after herself when she causes trouble.
He has a raging case of middle child syndrome. Having the overachiever of the century as an older peer shaped her into an extremely competitive machine. He's not so much motivated by hard work as he is motivated by recognition - he wants to be "the best" at something, and he's known to run himself ragged doing whatever's necessary to earn that title. She hates feeling shown up by her teammates, but she knows he's only the second strongest, second fastest, and second largest on the team. And while no one else measures him by those standards, it informs his attitude and self worth constantly.

History

In 1990, Muck was built on commission by a small group of freelancers. Since his design was so experimental, it took a couple of years of tweaking and rearranging and rebuilding before he was ready to work. Being built by such a personal group rather than an assembly line, she wound up slightly more developed than your average machine. He was kind of... gassed up at this time, and he daydreamed about outperforming other machines and about being lauded for having such a unique build. Her final design wound up not being a good fit for the commissioner, so the freelance group needed a new buyer.
Bob purchased him in 1993, making him the second machine to join the team team. She and Scoop immediately developed a sibling-like dynamic, and Bob was excited to have such a versatile machine on his team. He's always looked for creative approaches to his work, and he was easily able to work off of Muck's many strengths. Despite having an occasionally contentious relationship with Scoop and despite his budding self-worth issues, Muck was exceptionally well-cared for (as is the case with the entire team), and he quickly developed into the firecracker he is now.

Potential for Development

There is truly no one like Muck, both because he's such a unique character and in the sense that he's a freelanced one-of-a-kind design. This can make her feel incredibly isolated at times, which only adds to her hunger for recognition and attention. He truly believes that he's worth less than the other members of the team if he's not "better" than them in some capacity. She loves to compete, but she suffers so greatly when she winds up "losing."
He needs to learn how to appreciate his uniqueness and to stop treating his friends as reference points for success or failure. Sbe also needs to become a bit more emotionally independent.

Autistic Coding

Muck's special interests revolve most around soil science and geology. He keeps a rock collection, although he collects based on how interestingly they're formed rather than how pretty they look.
She loves to vocal stim by parroting or recording/playing back words and phrases, especially dialogue from YTPs. Since her sense of touch is so well-developed, she struggles with tactile sensory issues often. The worst offender is water, although it has more to do with being wet for long periods of time than with touching water at all. He doesn't mind a car wash quite so much if there's a drying tunnel at the end.
