Rodrick's Penpal

Rodrick's Penpal was a girl from Netherlands, she must be an adult since she was seventeen when Rodrick was in middle school. She was only seen in Rodrick Rules when Greg found Rodrick's letters from her in Rodrick's junk drawer, she hasn't been heard or seen since. This made Greg jealous because he wanted the same kind of penpal as Rodrick had, but he didn't get one.
