Otome's Crew is a group consisting of Otome, Lion and Bear. They all love art and are constantly chanting "go, go, art, go!". Otome is the leader. Lion and Bear are her underlings of sorts and do whatever she says.
They don't seem to have a home or a base, though they have an open area containing many statues and art that the Ham-Hams wreck in It's Art, Otome's Crew!.
They try to impress any hamster they meet by performing some form of act. For example in It's Art, Otome's Crew! they stack themselves on top of each other to create a tower, even though it ends in disaster.
