Kingdom of Knuffel

Me too. Bubbles are hard to find. lol.

It seems that Bubbles appear more frenquently in the Frostland Coast (water button).

At least it is stated so in
What digging items have you found? + Material Location Guide posted by Ziaheart.

Interesting. I don't have a whole lot of water knuffel.

It seems that always there are a fixed materials needed for quests.
Although it is not exact, this could be a guide

Rare: maybe almost all, but sure for Angel feather, Angel Tear, Gold Buillion and Books.
Uncommon: Goblin Ear and Darkness Potion.
Average: Cherry Blossom, Purple Candle, Saffron Flower.
Common: Holy Water, Bubble.
Prevalents; irrelevant.

That's interesting. I thought that they were always random.

And they are random.
But I supose there are a % higher in one element.
It is evident that water materials should be found in water button. The "problem" is in materials not easily recognizable as fork, for example, when a fork can sort out in earth, darkness, air, light, water or fire...

Huh. How about that. It's amazing how much thought they put in this.

i dig alot in water C:

Do you have a lot of water knuffel?

Furthermore that digging in water button the chances are increased if you dig with a water knuffel in it.
But I am not sure if this is definitive or not.
