Set in the world of the Hamtaro books and anime, the player controls the hamster ("Ham-Ham", as the hamsters tend to call themselves) Hamtaro. The game expands on the gameplay of the earlier titles by adding Bijou, a friend of Hamtaro who has a crush on him, as partner. Together, they have to save the other ham-hams from Spat, an evil hamster with a hatred for any kind of relation.
