The Legend of Zelda: Oracle of Seasons Glitches

Dialogue Mismatch
1) Beat the Poison Moth's Lair.

2) Go to the "Floodgate" guy and talk to him.

His dialogue will be that which Impa says when you begin the game, then he'll tell you where you can get to the keyhole from and then asks if you've opened the floodgates.

Translation Oversight
1) Find a sign by the Like-Like area, North-West of the Village and read it.

It is untranslated and still reads "Warning Like-Likes" in English.
