Mr. Gristle was a pretty important character. He was the first character to get approved through all the steps (design, sculpt, puppet, maquette, etc). We learned a lot about how to capture the looseness of the style in a human forum. In the end though, he was cut from the film as his personality became redundant with Crabs, the old name of what is now Mr. Gristle in the film. To add to the confusion, we more or less used his face for Sir Broderick the White Hat in the film. A lot can happen to the life of a character in a short amount of time.
The process for creating these images was a lot of fun. Head of Costume Deb Cook (no relation) asked me to help her with designing the costumes on the film. We constructed them as paper collages and touched them up with color digitally. Ripping and cutting paper really gave us interesting edges and made the costumes loose and expressive. Debs taught me a lot about the actual construction of a costume - not only does it need to look like it was constructed like a costume would in real life, it needs things like animator access and to be able to hold its shape. She could tell me if something I designed was too difficult to make or animate and we could go from there.
