Oméga, planète invisible/Planet Hydra IX and ghost ship

Planet Hydra IX
Hydra IX should be the 9th planet orbiting any one star in the Hydra constellation, possibly Gamma Hydrae, the second brightest one.

Role-play a stereotypical Frenchman (like the authors of this game): hunt and eat any kind of frog on this planet!

The canned food has expired, and it would make you lose 15 life points.

Hint
The only trustworthy character on this planet is the robot.
