The polka-dot donkeys are minor characters in The Backyardigans.
The Best Clowns in Town include five polka-dot donkeys in their circus act. Austin can lift a polka-dot donkey with just one hand. Unlike most minor characters in the series, the polka-dot donkeys appear in the backyard, outside of the Backyardigans' fantasy.
The donkeys are mostly white with rainbow-colored spots. Their physical appearances are similar to that of Molasses, Tyrone's burro.
The donkeys appear in one episode of The Backyardigans: "Best Clowns in Town" from season four.
