Nobody Plays 'It' Better - S2.E27

Professor Bufo has invented a rocket that goes very fast. Professor Bufo gets Oso to drive around a race track twice while being timed, but Oso suddenly crashes Bufo's rocket into a curve. That's when he receives a special alert from Paw Pilot and Mr. Dos. Oso teaches two kids at the park, Alexander and Elena, how to play tag. Will the three tag each other before Elena's mother comes to take her home?
