There are two known concepts for unreleased Tingle games.

Nintendo veteran and Tingle series producer Kensuke Tanabe has claimed that in 2010, a horror game starring Tingle was in development at Vanpool, but was scrapped for "a variety of reasons". This would lead to the development of Dillon's Rolling Western.

Tanabe has stated in a 2018 interview that he had an idea for a game about Tingle turning into a "super-powered being" that he had not yet had the chance to pitch. It is not known if this game was ever seriously pitched to Nintendo or entered development after the interview, however the shuttering of Tingle series developers Vanpool means that it is highly unlikely it'll see the light of day.
