Travis of the CosmosTravis first appears in Super Spore, having come to Earth to find employment. He communicates by retracting a tentacle out of his trunk and puncturing the back of other people's skulls, taking over their minds and using their mouths as a vessel to communicate. He does this many times with Shake throughout the episode, causing him to black out for long periods of time.

Chicken BittleChicken Bittle is the fourth member and brother of the Aqua Teens, and yet another one of Dr. Weird's creations. He's a chicken-shaped chicken nugget. He was made out of about a million chickens. He was in the process of carrying out another of Dr. Weird's schemes, involving crashing into a brick wall. However, Frylock diverted their course at the last minute. Chicken Bittle was eaten by a lion when they stopped in Africa. He can also be seen on Master Shake's pinball machine in the episode Eggball.

Chicken Bittle is one of few characters to die a canon death, and not come back to life.

He was the youngest of the Aqua Teens, but the first to have died.

He was the only Aqua Teen loyal to their insane creator/father, Dr. Weird who eventually becomes the others' moral enemy.

RobositterRobositter (voiced by Sarah Silverman) is a teenaged girl robot babysitter that Frylock created for Meatwad so he can keep his little ass in line while Frylock and Master Shake are at work. Her body is built from a water heater with breasts made from cans and arms made from dryer vent hose. Shake appears to be attracted to her, asking her was she legal and what will you be wearing to bed. Despite responding in a pleasant and obedient tone when Frylock is present, she immediately begins acting like a psychotic and stereotypically selfish teenaged girl once Frylock leaves, abusing and threatening Meatwad and talking about shallow things on the phone to her friend Sheila.

Frylock later meets up with Robositter and Sheila (another trash-can robot) at the mall, who are wearing thongs, wigs and belly shirts and generally looking like little tramp(s) as Frylock puts it. After having abandoned Meatwad to demand her babysitting money early from Frylock (so she and Sheila can get tattoos just above their robot asses), she rudely insults him for his job and Frylock promptly crushes her and Sheila in the Slurp-a-Lunch juicer machine. Shake protests, noting that he was supposed to buy them wine coolers.
