Putt-Putt was originally thought up by Shelley Day as a series of bedtime stories for her son, Travis; the first story involved Putt-Putt saving a cat caught in a tree. Child actor Jason Ellefson did Putt-Putt's voice for the first eight of the games. In the games released between 1998 and 2000, Nancy Cartwright (of The Simpsons fame) voiced Putt-Putt. Michelle Thorson voiced Putt-Putt in Pep's Birthday Surprise. The games are supported by ScummVM and thus can be played on other platforms such as handhelds. Humongous has brought several Putt-Putt and other titles to iOS and Android. In 1997, Humongous made an agreement with Lancit Media Entertainment to create an animated TV series of Putt-Putt, along with movies and home video releases. However the plan was never put into action. Several games from the original series were later re-released by Humongous on Steam in April 2014, alongside games from the Pajama Sam, Freddi Fish, and Spy Fox series.
