Final Fantasy Crystal Chronicles: rings of fate HELP!

I am stuck in the second poison room in the Final dungeon (first play through.) I defeat all the mobs i can, the key appears, but i can't find the lock. The giant wodden thing is in my way and it won't move or anything. PLEASE help, I'm almost done the game but i'm stuck here.

Yeah I got stuck on this as well. You need to get back to the previous room with all the red and blue switches etc. that block your passage, and there is a lever type thing in the top leftish corner of the room. Pull it backwards, and then go back into the room. The wooden wall should be removed :)

THANK YOU! THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU!THANK YOU! U have NO idea how frustrated I was. Lol, i beat the game now. Thanks for the quick reply! :D

You're welcome :) Just try not to post in all caps next time and spam the same thing over and over again.

Sorry...
