Dexter (めがねくん, Megane-kun) is a short, well-educated hamster. He is the rival of Howdy but is willing to help him on occasion. He has a crush on Pashmina. People also say his laugh is cute. A dapper dandy, this well-mannered, gentleman hamster is always smartly dressed and ready to help.
Owned by Curtis. A refined hamster, who is incredibly smart. He loves Pashmina, but often battles with his long-time friend, Howdy, for her affection. He may know Latin, because he offered to make a club motto in Latin for the ham-hams when they first were making the Clubhouse. His Japanese name is a pun: Megane means "glasses" in reference to the tan markings of fur around his eyes that makes him look like he's wearing glasses. Coincidentally, his owner is an optometrist.
In Hannah is in Love!, Howdy's old friend Hannah had a short crush on him, but he seemed to not have an interest in her romantically, although he said she was pretty.
