He used these robots, and the Flynn-Fletcher family robots, in order to fight Perry the Platypus and the recently recruited animals of Africa, in order to use his paws to unlock the main computer of the O.W.C.A. (Where's Perry? (Part Two))
They physically resemble their organic counterparts, but their sclera are always red instead of white.
While Perry was trying to get away from the evil Carl, the two met up anyway and Perry then looked to his sides with wonder. Carl asked if he was looking at the robots, and the camera panned out to reveal the robots of the Flynn-Fletchers alongside many new other robots. Carl then mentioned that he made them (the new robots) in his free time.
A construction sequence was never seen, so either Carl made them really fast, or he build them while chasing Perry.
The robots, alongside the Flynn-Fletcher family robots, were destroyed in the battle with he recently recruited animal agents. Their remains, including the robots of the Flynn-Fletchers and the Highly Unconventional Vehicle, were taken back to the O.W.C.A. headquarters to be repaired.
The robots share many abilities found in many other robots seen in the series: They're pretty durable, and pretty strong as well.
They can also change their various body parts into different weapons, like blasters and so on.
They follow his orders with little to no hesitation.
