Hamtaro Nazo-Nazo Q!
First Hamtaro game for NDS - here a lot of new hamsters appear that we don't see in the English series. It's in Japanese.
In this game, well... I don't know exactly what's the story here, but seems like some kind of evil boys kidnapped a princess in a floating castle. She dropped a book that fell on Sorahamu-kun (Sky Ham), who was flying, and he falls to the ground. Then a Ham called "Nande-kun" (Nande means "What" or "who") appears, who will help the Ham-Hams save the princess!

Hamtaro: Haai! Ham-Ham Challenge! English
Japanese
Second Hamtaro game for NDS, availalble in English :D Here we only see the main 15 Ham-Hams, but in a Haai! style. Haai! is the last "season" of Hamtaro, featuring little short animations of 5 minutes.
In this game you need to play a lot of easy -but still fun- minigames to get postcards :D
