Fish drugs might be a good idea. On Earth they've got that pufferfish that you need a special chef to prepare. If there are fish here on Planet Blue, maybe one of them has drugs in it. Plus you're pretty hungry from the wormhole travel.
You find a nice flat stump or something. You can't really tell what it is. In truth, you're having a pretty hard time making sense out of anything you're looking at, what with everything being blue here. But it's wide and flat and firm so you take a seat and think. What to fish with?
