Ammoses Shellendorf(NA)[a], or Ammoni Shellendorf(EU/OC)[b], is a minor character in Splatoon. He is Sheldon's grandfather, or "grandpappy," as Sheldon calls him, and the founder of Ammo Knights.[1]

His status and location are unknown, as he has never been seen in person in-game.


Ammoses Shellendorf served in the Great Turf War as part of a division called the Squidbeak Splatoon alongside Cap'n Cuttlefish, Judd, and two unidentified Inkling soldiers.

At some point, Booyah Base was built around Sheldon's home and weapons shop. However, it was not him, but Ammoses Shellendorf who owned the land at the time.[2] This suggests that Ammoses Shellendorf may still be alive, as Sheldon appears young enough that these events could have happened fairly recently.

In his later years, he worked on peaceful applications of his weapons.[1]

In the manga

Ammoses hid a treasure atop of Mount Nantai, a weapon that resembles a Splattershot but far more powerful.


Ammoses Shellendorf designed many anti-Octarian weapons, ten of which are known:

They are unlocked by collecting Sunken Scrolls in boss missions.



Ammoses is derived from ammonite, a type of mollusk, and ammo, a clipping of the word ammunition. The latter definition references his career as a weapon engineer. Shellendorf is derived from shell.
