Lead your rat to the gold medal!

...They live not far from your house. Just over the fence from the last cottage on your street there's a dump... Not a romantic place, dear Sirs and Madams, but that's where they live. Recently these creatures have decided to organize their own Olympics to let the world hear of them. We don't know why but javelin-throwing seems to become rats favorite sport. Are you ready to reincarnate in one of them and master your throwing skills?
