Card Trivia:Grandpa Demetto (card)
- This monster appears in the artworks of "Doll Happiness" and "Doll House".
- The roof of "Doll House" appears in this card's artwork.
- This card's effect to Special Summon Normal Monsters from the Graveyard as Level 8 DARK monsters reference how Grandpa Demetto, as part of the "Doll House" Field Spell Card, was responsible for fixing Cologne's "Doll Monsters" whenever they were destroyed, causing their Levels to increase and for them to take on more hideous and gothic appearances.
- Changing the monsters' Attribute to DARK allows them to be used as Xyz Material to Xyz Summon "Number 22: Zombiestein", as Cologne did in the manga.
- This card is based on the character Grandpa Demetto from the Yu-Gi-Oh! ZEXAL manga.
- This card's OCG/TCG artwork is taken from Yu-Gi-Oh! ZEXAL Rank 16: "The Third Enemy!!", specifically from the panel where Grandpa Demetto makes his first appearance, although his right eye is no longer hanging from its socket and the face of the doll he is holding is turned away from the viewer.
