In Yuri!!! on ICE, Viktor has a tissue box in the shape of his dog Makkachin, which he uses when coaching Yuuri. Is there any indication whether this is based on Yuzuru Hanyu's Pooh Bear tissue box? Have any statements been made by the creators about that?
Actually, the Makkachin tissue box was inspired off of Johnny Weir's old Russian cartoon themed tissue box.
Many elements from the show were inspired by him as well from the tissue box, to the flower crowns Viktor wore, Viktor's custom gold blades, and right down to Viktor's feathered costume. All of those things were known and inspired by Johnny. The feathered costume came from his first Olympics as a swan skating to Swan Lake. Every time he won a comp. Johnny got a flower crown, and Johnny's favorite color was gold so he got custom made gold blades.
All of these were inspirations from Johnny Weir.
