When Neil's son Will touches the rock, he is shrunk down to a microscopic size and enters the wacky world. Neil also gets shrunk down while trying to rescue Will. They meet the crazy yellow orb Astronut and his green blob friend Blurp who lead them on hilarious adventures. However, Neil and Will want to return the micro-verse to space and restore their normal sizes before the silly world spreads. But Astronut and Blurp want to have some fun with their new giant friends first.
