Luffy, Ace and Sabo were going about their usual mischief until Garp turned up, and attacked them for still wanting to be pirates. The brothers decided that they would have to run, or Garp would kill them the next day. During the night they run and end up sleeping under a tree. In the morning, they decided to build a hideout, so they went to the Gray Terminal to get some materials. Once completed, their hideout looked like a pirate ship.
