Grandfather lives with his spouse deep within a secluded, snowbound forest. He exhibits robust physical vitality through active tasks like assisting with woodcutting and tending to Pokémon.

He shares a significant bond with the resident Slugma, possessing deep knowledge of its behaviors. He understands its shy disposition and habit of retreating into chimney pipes. Grandfather deciphers Slugma's smoke signals—interpreting two puffs from the chimney as a display of happiness—and later explains this communication method to his granddaughter Anna.

His practical care for Slugma includes regularly clearing accumulated rock formations from its body. This maintenance coincides with cooperative household routines, such as directing Slugma to heat the cooking oven. His responsibilities extend to other Pokémon, including polishing a Haxorus's blades after wood-cutting sessions to maintain its capabilities.

Within family dynamics, Grandfather serves as a patient guardian. He reassures Anna when she expresses disappointment over Slugma's elusive nature, countering her concern that the Pokémon dislikes her. He guides her search by suggesting possible locations like the backyard. His partnership in household management involves shared duties, including childcare coordination and external tasks like wood preparation.
