The new lineup was later renamed "Disney's One Too" in July 1999, formatted to serve as a competitor block to ABC's existing children's block "Disney's One Saturday Morning". The block debuted on September 6, 1999, replacing UPN Kids, which ended its run the day before (on September 5) after four years. Compared to the format of "One Saturday Morning", "One Too" varied in that, instead of incorporating hosted segments, short gag segments from the shows featured in the block (such as "", "Doug" and "Recess", all of which – along with a few other series – were originally aired on "One Saturday Morning") were usually shown, often preceding the start of each program, and after commercial breaks. The block also featured a different opening sequence, using more futuristic buildings and a theme similar to that used on "One Saturday Morning". Many shows previously aired on "One Too" continued in reruns on Toon Disney and Disney Channel.
