FANNY PAC

Two teams (red and blue) of two hovercrafts have 218 seconds to capture as many ping pong balls as possible. Capturing ping pong balls is done by herding or pushing the balls into the appropriate camp... But there's a catch: after 45 seconds, the current pairing between hovercrafts and controllers becomes obsolete and controllers must switch to a different hovercraft. This cycle is repeated until the game is over... Build a hovercraft and controller where each can pair with those of any other team.
