Zhu Zhu Pets Rockstars Roxie. We chatter, scatter, scoot n’ scurry while making tons of hilarious sounds! Zhu Zhu hamsters don’t poop, die, or stink, but they are a riot of motion and sound! Darting around in their hamster tubes, busily scurrying from room to room, you never know where they’ll go next! Simply pet the hamster’s back, set him down, and watch him ZhuZhu Zhu-oom! These hamsters have over 40 different sound effects, depending on the unique environment they encounter.
