Also, don't do a Nuzlocke. They make you die of heartbreak.

You want to know something not to do? Don't look in the captain's bin.
Especially after eating.

Eating that odd-looking pink jelly you found in the sme place a pokemon was a few seconds ago. And by odd-looking, I mean it has eyes and a mouth.

If that makes any sense.
