Take the hoverboard from the girls
From Create Your Own Story
You take the hoverboard. As you start to adjust to riding a hoverboard, you narrowly avoid bumping into two bystanders and subsequently dodge a large rock, which causes you to fall off of the hoverboard. Quickly getting back up, you see Griff's gang coming after you on their own hoverboards. Jumping back on the hoverboard, you made your way onto the street, with Griff's gang closing in on you. You are nearly caught by the gang, but managed to grab onto the back of a Jeep that had just landed.
Grabbing a rope from the back of the jeep, you begin trailing behind. After narrowly avoiding hitting the crowd, you notice that the jeep had turned a corner to the Cafe 80's and you see an angry Griff about to hit you with his bat. Fortunately, youonce again managed to dodge out of the way, which resulted in Griff hitting the tail light of his own car instead. You then notice an incoming car, but fortunately manage to hover over it and end up hovering over the artificial lake, nearly making it the whole way across.
Unfortunately, as you make your way across the lake, you noticed that the hoverboard is slowing down, eventually coming to a complete halt about a meter from the other side. Griff's gang mock you. Apparently the type of hoverboard he was using does not work on water.
