Cappy (かぶるくん, Kaburu-kun, Spanish "Gorritas") is a white and brown ham ham, and one of the youngest. He wears a green cap. He loves to put different things on his head. One notable thing would be a pan. Cappy has a passion for hats.
Shy and hesitant, he is always looking for something new to put on his head. He's willing to try all sorts of things, but standard saucepans are his cap-of-choice. He is owned by Kip and Sue. The two hats Cappy most commonly wears are his green swimming cap and the giant red saucepan that he usually hides under. While he loves his home, he does not like being spoiled. He also looks up to Boss due to his independence as a field hamster.
He has developed some sort of a rivalry with Stucky, especially when it comes to hide and seek. Soon he becomes Cappy's best friend (as shown in the episode Stucky's Tunnel and later on in the game Ham-Ham Games as he is always searching for him). In later episodes he is always willing to help Stucky, for example in Lovestruck Stucky and in Where Are You, Cappy?
In Ham-Ham Heartbreak, Spat steals the acorn hat from Seedric and gives it to Cappy. When Hamtaro convinces Cappy to return it, he decides not to at first, but later realising how much he could be missing his hat, he returns it to Seedric himself. Through this they become good friends, both sharing a likeness for hats.
- Cappy shares a Birthday with Hamtaro (August 6th) as stated in the Happy Birthday Hamtaro Special!
- Cappy is never seen without his green swimming cap apart from in Get Well, Laura where he takes it off to help fan Laura, and First Time at the Beach, where he takes it off so he can wear a seashell.
