So I've been looking around the web to get my hands on two rare monsters that don't seem to be obtainable by normal means. I have yet to find any Action Replay codes for getting these monsters.

The monsters in question, Geemo and Woodie
These two monsters have their descriptions fully translated into English in the US version. Though I've came across conflicting forum posts on if they can be obtained in the US version without freezing the game. We have no actual codes to obtain individual monsters yet and the fill encyclopedia code doesn't add these two in.

Also, while looking around, I found out there are apparently two more monsters that are unobtainable:

These guys completely lack any sort of description in the US version. I'm not even sure if they work or not either in the US version.

Now if someone can research this and figure out AR codes to make any monster you want generate through combining or using the drawing/incantation/Spellbook, that would be great. Thanks.
