Papyghetti

Papyghetti is the cargo ship between Papyrus and spaghetti from the Undertale fandom.

Canon
Papyrus learned his (bad) cooking skills from Royal Guard leader Undyne. As Undyne felt like Papyrus was too kind to be a member of the Royal Guard, she started giving him cooking lessons instead of training him for the Royal Guard.

Papyrus has cooked spaghetti many times. Although his cooking is considered bad, it has imporoved, as the spaghetti he cooked eventually became edible. Papyrus never eats his spaghetti, and instead assumes others love it.

Fanon
Due to Papyrus' association with spaghetti, Papyghetti is among the most popular cargoships in the Undertale fandom.
