Mike has patches of grey, black, orange, and white fur and a pink snout and buck teeth. He appears to be on the overweight side.
According to the model sheets, he's 5 1/2 ft all.
He is seen wearing a light green button-down collared shirt, navy pants, brown belt, and brown loafers.
Little is known about Mike's personality. He seems to be lacking any business sense because he and Morgan went out of business due to their ridiculous business plan.
In The Kidney Stays in the Picture, Todd's stepfather Jorge tells him his mother Helen is sick and she needs his kidney. Todd tells Jorge he would give his mother his kidney, but he sold it for sockpuppets.
Jorge, Todd, and Ruthie then show up at Mike & Morgan's House Of Organs. Mike welcomes them and Morgan tells him to give it a rest. Todd asks what's with all the boxes, and Mike tells him they're going out of business. Jorge tells them they are trying to track down his son's kidney, but judging foolishness of their business plan, they probably don't keep records.
Morgan then tells him all their kidneys went to Chicago because Whitewhale bought them out. When questioned by Jorge on why she then tells them Jeremiah Whitewhale is stockpiling organs because he's a rich old guy who wants to live forever.
Jorge says this excursion was pointless and he's heading back to the hospital. Todd apologizes for not being more helpful. Jorge says no, it's his own fault for believing things would be any different.
Todd decides he wants to buy a gigantic barrel of anesthesia. Jorge wakes up in Chicago, in Guy and Diane's apartment, after being knocked out and kidnapped by Todd. They all then make a plan to sneak into the Whitewhale building and retrieve Todd's kidney.
