Illidanz: The diner is above pluto, way above the sea.
Keep on starsliding when you see stars, by pressing up while being straight upwords, nose facing the sky. That makes a "starslide". After getting 4 or more starslides, do a tail slide in the water when you still have a tiny bit of time. You will get boosted very far. Keep on starsliding until you get to the diner. :3
This is EXACTLY like the game "there's 2 wires", which is also on the site. Even has the same background/gameover seen. Somebody should go figure out why... :C
