At the Nico Nico Douga Daikaigi 2010 Summer: Egao no Chikara event, YAMAHA, Fuji TV Kids, and the Internet Co. Ltd. music and software company announced that they would release a new voice pack for the Vocaloid2 singing simulation softare. The pack will be based on the Gachapin character from Hirake! Ponkikki, a popular Fuji TV kids' program which ran from 1973 to 1993. The "Gachapoid" Gachapin x Vocaloid voice pack CD will be released on October 8 with a special green case and a free six-month subscription to Nico Nico Douga's premium paid service.

Gachapin also has a second identity, "Gatchapin," which is the buck-toothed green dinosaur dressed up as a character from the 1972 Gatchaman anime. This version was later immortalized in figure form. Gachapin also made a cameo in the “Read My Mind” music video by the American rock band The Killers.
