Hi I am at chuckola woods and I am in the barrel place and I don't know..

Go into the chateau de chucklehuck place where the barrels are and make sure that mario is in front. Go up until you cannot go you p anymore, then go right all the way, then up again all the way, then left all the way. You should be at the place where you can see mario and luigi. Go down all the way, left all the way, down all the way, left all the way, up all the way, right all the way, up all the way. You should be in another gap where you can see both mario and luigi. Then move right all the way, down all the way, left all the way only when you see the exit, and move down. When you get out of the barrels, the person behind you will not be luigi, it will be popple. Hope I helped ya
