Toothlightccup

Toothlightccup (also known as Hicctoothlight) is the name for the threesome pairing between Hiccup Horrendous Haddock III and Toothless from How to Train Your Dragon (2010) and the Light Fury from How to Train Your Dragon: The Hidden World (2019). It is not a popular pairing within the fandom, but it does have a few fans. As one of the more unorthodox relationships in the fandom, this can be considered an amalgam of the Toothcup, NightLight, and Lightccup pairings.
