Hannah

Hannah is Howdy's childhood friend. She is one of the very few who can stand Howdy's jokes. In fact, she claims to find them endearing, and knows every one of his jokes so well that she can state the punchlines before he does. All of the Ham-Hams think she is pretty.

In Hannah is in Love!, Hannah comes to visit Howdy, and is introduced to the other Ham-Hams. During her short stay, she developed a crush on Dexter; in part due to Dexter's "flattering" correction of calling her "just perfect". Hannah and Dexter went on a date in the Ham-Ham Fun Park together; but Hannah decided that Dexter was a "wimp" because of his cowardly reaction to the rides. After their date, Hannah's crush on Dexter died out.

In the English dub, she has a soft voice with a country accent.
