Here is a pic to show you how things can change. This is from the Frankenstein's Cat series. The robot on the left was the initial design for the Depickler, and on the right the updated and used design. The depickler was the product of 3 things been mistakenly thrown into one of Dr Frankenstiens experiments. They were a pickled herring (there is always a pickled herring in each episode), humbugs and another one of Dr Franks experiments the homework detector.
