Minka Mark is a very peppy little monkey, and to top it off she's also very hyper. She loves to spends her days painting and chatting it up. Or searching someone's head for food while they speak to her. Most-likely because she is a monkey, she just can't help but be distracted by even the simplest of things. Though it could also just be because she's too hyper to pay attention to one thing for long amounts of time.
Minka's passion lies in art however, but not just any art: Abstract. There is nothing she lives more then just grabbing a few cans of paint and throwing it around at anything nearby, be it a canvas or a window.
It has been revealed, however, that she cannot work under stress or pressure. When she realized that by selling her art and that it would no longer be fun, she went through a small meltdown that took Russell's apology to make her feel better and resume painting.
In episode 9, "Dumb Dumbwaiter" It is revealed that she is highly claustrophobic when trapped in the dumbwaiter stating that she was a "space monkey" and went as far as screaming when in panic.
