Knight's help, Kirby and Prince Fluff confront and defeat Yin-Yarn, breaking the spell and returning both Dream Land and himself back to normal. Prince Fluff parts ways with Kirby, stating that he can visit Patch Land anytime via Yin-Yarn's magic sock. Development Kirby's Epic Yarn was developed by Good-Feel, and was the third game developed by them in conjunction with Nintendo, following the releases of Wario Land: Shake It and Looksley's Line Up. The idea of a "world of yarn" was proposed by Madoka Yamauchi, the Planning Section Manager of Good-Feel, and ideas for the game mechanics grew after the staff experimented with store-bought cloth. The game began development under the name Keito no Fluff (lit. Fluff of Yarn), featuring Prince Fluff as the main character. During the summer of 2009, Nintendo proposed that the game be altered and released as a title in the Kirby series, though Prince Fluff remained a part of the final product as Kirby's partner. At least three months were spent focusing on Kirby's movements and character design. The game's development was overseen by HAL Laboratory's character production section, as well as Warpstar inc., a company put together in 2001 to manage the usage of Kirby. To create an "authentic feel" for the cloth and textiles, the graphics were created by using digital photographs of fabric, which were placed under polygons. The game's soundtrack was scored mostly by Tomoya Tomita, while franchise regulars Hirokazu Ando, Jun Ishikawa and Tadashi Ikegami handled the musical reprises towards the end of the game. As the original plot for the game involved a timid Prince Fluff searching for his lost mother, Tomita originally hoped to create a "new kind" of feeling introduced in the game's opening: soft and sweet, yet also sad and unsettled. However, the game turned out to be more conventional than he originally planned, so he changed direction to slightly richer arrangements. Kirby's Epic Yarn was officially revealed at Nintendo's press conference at E3 2010, where it was announced to be released during the autumn that year.
