I have been playing Wizard 101 for three years now and I still have not found the little blue oyster in Mooshu at the Tree of Life.I found the rest of them but I have been through the Tree of Life area many many times.If anyone out there has completed that quest in MooShu please let me know where it is at in Tree of Life.
You should be able to find the answer by doing a quick search on the boards here, but it is basically across from the tree at the base of on one of the walls. Not positive, but I think it's the one opposite the area where the portal opens. Good luck!
It is before you get to the tree.Go down the step on the opposite side of the ladies dressed in black along the wall.I walked the area 10 times before i found it.That was the last 1 i needed finally got it.
