[1][2] Uglydoll started with a letter Horvath wrote to Kim after she had to move away due to an expiring student visa.

The letter had a cartoon of his character "Wage" at the bottom with the words, "Working hard to make our dreams come true so we can be together again soon," next to it.

[3] The Uglydolls were created in 2001 and included Babo, Cinko, Ice Bat, Jeero, OX, Target, Tray, Wage, Wedgehead, and many more doll characters.

The original creators, David Horvath and Sun-Min Kim, were set to executive produce.

In May 2018, Hulu signed a deal with STX Entertainment to produce an animated television series based on UglyDolls.
