He also has a small speaking role working at a street market booth in Hamtaro: The Captive Princess, although his markings are different from how they appear in the games.
Hamstarr makes his first-ever game appearance in Tottoko Hamutaro: Tomodachi Daisakusen Dechu. He helps tell Hamtaro and his friends (and the player) their fortunes through a book and who they will end up being in love with.
In Rainbow Rescue, he has his own mansion. Howdy was working part-time at his place in exchange for a purple marble, which the Ham-Hams needed for Prince Bo's rainbow. He also appears on the Ham-Ham Clubhouse's television in a program called "Hamstarr's Horoscopes", where he will tell the daily horoscopes.
In Hamtaro: Ham-Ham Games, he can be found in one the Ham Studio's rooms. He appears on TV again in which he tells others' fortunes. Listening to his program can get the player costumes or sunflower seeds.
