Once you've beaten Wizpig the first time and gotten the Gold Trophy in all the Trophy Races, you'll be able to venture into Future Fun Land. The first time, you'll lift off from the lighthouse on the coast of Timber's Island. After that, the lighthouse's foundation will serve as a teleporter to Future Fun Land's lobby.
