Owned by Maria. She is a somewhat unworldly hamster who loves her blue ribbons, but she is not above getting dirty when she needs to help her friends, and has been known to be generous and helpful.

She used to live in France before moving to where she is now, but she feels attached to Japan and has even refused to go back to France. In the Japanese version, she speaks normal Japanese and adds the words 'dechuwa' (most likely a hamster version of "desu wa") at the end of her sentences, while the American version of Bijou has a French accent, because, "Bijou," is French for "jewel," which is one word to accurately describe her personality. She also has a crush on Hamtaro, though he is quite oblivious to this fact.
