Professor Mixelpuss is an unseen character in Mixels.
Not much is known about Professor Mixelpuss' appearance. His is color scheme and design from the legs-down is unknown. However, his statue shows that he has a long jaw with five teeth pointing upwards. He has a double segmented body right above his jaw, which contains his arms in a T-shaped socket. His arms are long and striped, with somewhat extended pincer hands. On top of his body is a round dome with round decorations on the bottom of it. He wears a mortarboard cap on top of this, with two ears poking out of it. He has four eyes, with two of them connected to his face, and the other two connected to his other eyes via stalks.
- His statue was the focus of the first building challenge on the LEGO website.
- He is possibly deceased, with the statue in honor of him.
- He, the Misical Muxels, the Maximum Mixel, and the Advertisement Mixel are the only characters that weren't seen in their real forms.
