Ammoses Shellendorf

Ammoses Shellendorf❌, or Ammoni Shellendorf, is a minor character in Splatoon. He is Sheldon's grandfather, or "grandpappy," as Sheldon calls him.

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

History
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 he but Ammoses Shellendorf who owned the land at the time. This suggests that Ammoses Shellendorf may still be alive, as Sheldon appears young enough that these events could have happened fairly recently.

Weapons
Ammoses Shellendorf designed many anti-Octarian weapons, ten of which are known:
 * Custom Splattershot Jr.
 * Kelp Splat Charger
 * Aerospray MG
 * Aerospray RG
 * New Squiffer
 * Dynamo Roller
 * Gold Dynamo Roller
 * Hero Charger
 * Hero Roller
 * Hero Shot

They are unlocked by collecting Sunken Scrolls in Boss missions.

Trivia

 * His first name may be a reference to the fact that he owned Ammo Knights before Sheldon.
