I can't complete the coffee task because I didn't go to Dali during the card tournament! This is a blow!
Also, where do I get the second pumice piece?

There are a few Pumice Pieces.

1) Defeat Ozma for one
2) Find some on Chocographs
3) I believe you can Hades to synthesise one for you

Also, you can't complete the coffee task now, so why tell us?

I can't complete the task now! Argh! That means Morrid will die and I already feel so bad about telling those two Clerya oracles or whatever to go the wrong way and got them fried.
Well, I got another pumice piece from a chocograph.
I can't seem to find two chocographs now (I have dug them all up and got the golden choco). "Ocean" and "abandoned lagoon". I think I will go try find some help now.
EDIT-Oh good, I found a choco-map!

EDIT2- What the heck? I have looked at the position and dug about there for 5minutes! Why is it so difficult to find!?

EDIT3-I found an actual picture, it was near the island! Those maps were well misleading.

You get excited really really fast, don't you?

haha
