S04:E13 - Balloon Train / Dolphin Dilemma

When a boy and his grandmother board a luxury train in South Africa with self-inflating balloons everyone gets a very different ride than they imagined. The balloons, which are for a friend's birthday party, aren't meant to be activated until after the journey, but some animals get aboard and cause the balloons to inflate, sending the surprised train up into the sky.
