Initially assigned as a supervising animator on "The Lion King", Nik Ranieri did character designs and test animation for Timon, but moved over to "Pocahontas" growing frustrated with an indecisive vision from the directors. There, he was assigned to animate Redfeather until Jeffrey Katzenberg ordered for the animals to be mute. Finding feathers difficult for Redfeather to gesture with, he was again assigned to animate Meeko using a Little Golden Books animal book illustrated by Alice and Martin Provensen as reference. Duncan Marjoribanks utilized geometric shapes to create Ratcliffe. In early drafts of the character, he had the body similar to a pear, but to make him appear more arrogant, the animator increased the force of gravity on his chest so that he seemed more pompous and physically threatening. Chris Buck served as the supervising animator for Percy, Wiggins, and Grandmother Willow. For Grandmother Willow, the face was traditionally animated by Buck, while the cowl and the trunk of the tree was digitally animated under the supervision of Steve Goldberg. Assisted with the effect animators, a 3D software program was employed for the bark to be individually manipulated and for the face to match with the computer-generated texture. The following supervising animators included Anthony DeRosa for Nakoma, Michael Cedeno for Kocoum, Ken Duncan for Thomas, T. Daniel Hofstedt for the settlers Lon and Ben, and Dave Pruiksma for Flit. While "Mulan" (1998) was within its pre-production stages, 18 minutes were animated by 170 animators and artists at the Disney-MGM Studios.
