Thanks, I think I know all I would ever want to know about Blue Potions in WW.
Back to the topic at hand, I don't have any problem finding more than one Rare Chu. I have found and scooped up at least half a dozen. My problem is that if I have a bottle of Rare Jelly in my inventory I can't for the life of me find another Rare Chu.
Normally to find a Rare Chu I just jump in and out of a grotto with a Chu in it until I get a rare one. Easy enough right? Usually I get one with in 3-5 jumps.....unless I have a bottle of Rare Chu Jelly already. Then it's like the goddesses feel like punishing me for being greedy or something.

I spent an entire afternoon doing this once to no avail. I got so frustrated I find getting multiple Fairy Tears from the Cave of Ordeals easy by comparison. Right now I have one bottle of Rare Chu Jelly and three bottles of Fairy Tears.
