Hobbit no Bouken, translating to 'The Hobbit's Adventure', is a Game Boy Advance game by Caravan. Given the title, it likely features a storyline based on the adventures of hobbits from the Tolkien universe (though this is not confirmed).  The gameplay is speculative, but may involve adventure elements, puzzle-solving, or possibly even light RPG elements. The publishing by Caravan suggests a Japanese market release.
