The logo for the Pokémon Center in Tokyo featured Poliwhirl until it was replaced by Piplup in July 2007.
Poliwhirl was also featured prominently on the center of the November 22nd, 1999 issue of Time Magazine.
Poliwhirl's sprites and artwork are inconsistent with respect to its gloves. Sometimes they are depicted as mittens, while other times they have separate fingers.
All spritework from FireRed and LeafGreen onwards feature Poliwhirl with mitten-like hands. Because of this, Poliwhirl is one of the few Pokémon to have its Emerald sprite differ from the Ruby and Sapphire one.
