In Polandball comics, animals sometimes make a cameo.
Canadaball is sometimes seen battling a Canadian Goose, portrayed as a fierce goose. It often beats up Canadaball, yet he's the best one at handling it.
These animals are often seen dead. Next to Canadaball, holding a bloody wooden club. This is known as seal clubbing.
Spainball can sometimes be seen with bulls. This is because of the famous 'Running of the Bulls'.
Bald eagles often appear when USAball is around. This is because the bald eagle is their national bird. USAball is usually seen protecting it, toting it around, or discussing how "epic" it is.
These animals are often seen with Philippinesball because when Malaysiaball, Indonesiaball, and Tringapore say "Selemat Pagi" (Good morning in Malay), Philippinesball confuses it with "Thank You Stingray" as (Pagi is stingray in Filipino). Cayman Islandball's beaches are well known for their abundance of stingrays, giving them the nickname 'Stingray City'.
Seen once with Philippinesball and Chinaball, in which Chinaball accidentally incinerates the poor creature into Siopao (Baozi). This is a based on a Filipino speculation that Siopao (or any other Chinese food sold in the streets) are made of cat meat, dog meat, rat meat, cardboard, or plastic. Japanball is always going about his kawaii cat costumes. In one comic he teaches Polandball how to be kawaii and Polandball tells Germanyball about 'how to kawaii'.
