Piles the Beaver is one of Cow's dolls alongside Crabs the Warthog and Manure the Bear. Like his fellow dolls, he is actually alive but only moves when Cow is not around. Piles is an imbecile who easily gets on the nerves of Manure due to only being able to speak when his string is pulled and is constantly asking for others to pull his string despite never saying anything outside of his usual idiotic catchphrases. In Cow's Toys, he was left at the house next door by Manure for his annoying idiocy.
- Piles has his own TV show as seen in The Great Pantzini.
