Twist the TrackBall's blue button to activate 6 different features - take MiPosaur for a walk in 'Leash' mode, or satisfy its appetite with virtual tasty treats in 'Food' mode. The TrackBall can also be a pet toy for MiPosaur to chase, and MiPosaur can even dance and beatbox too.
MiPosaur will respond to being treated nicely as well as badly - if its tail is pulled, MiPosaur will react annoyed. Put MiPosaur together with MiP and the two can interact together. MiPosaur follows hand gestures and can also be controlled via a free Android or iOS app.
