Like most other cartoons, the animation was outsourced to other countries. This was mainly done for cost purposes and the limited availability of artists in the United States. All the writing, music, direction, character design, and color was worked by around 30 Disney employees in Hollywood. After this, everything was sent overseas for the animation. Approximately 300 employees would work on inking and printing. An unusually high number of animation cels were used for the show, with 20,000 cels in each episode as opposed to 8,000–12,000 for typical cartoons. The show had more drawings per minute than any other television cartoon at the time. Early episodes were completed by TMS Entertainment in Tokyo, Japan and later by Walt Disney Animation UK Ltd. in London, England, Hanho Heung-Up in Seoul, South Korea and Wang Film Productions in Taipei, Taiwan. Sixteen episodes were also produced by Walt Disney Television Australia in Sydney, New South Wales. The show set a benchmark for similar cartoons that both Disney as well as other channels expected for future shows. In Manila, Philippines, Fil-Cartoons (subsidiary of Hanna-Barbera) and Toon City also contributed some animation for the series.
