Oh god the Pokemon rumors

THE POKEMON RUMORS.

When I was a kid my brother told me a rumor of a hidden island with one more gym trainer, your dad, that was south of cinnabar. In order to get to it you had to destroy the buoy things that're south of the pokemon center's doors. How to do that? Keep hitting it nonstop for 15 minutes straight. If you stop once, you're done.

I don't really remember any others, and for some reason we avoiding learning about the truck, but that was pretty dickish of my brother.
