You decide to cut your losses for now, and focus your time on a more profitable venture instead. You ask Moonflower if she knows any plants that yield blue pigments.

Moonflower: "Yuh uh, I know a few that are good for dyes, but blue is kinda rare. The ones I know are from the Everfree Region, though. Maybe Azure Spark knows what we can use around here."

You concur, and bid farewell to Ruby Heart.

Ruby Heart: "Get well soon!"

You walk over to the next stall, where you find a familiar shopkeeper surrounded by hundreds of adorable stuffed toys. According to Tattle Tail, that would be who you are looking for.

Azure Spark: "Yo."

You greet Azure Spark, and ask her about the blue pigments she needs. She responds slowly but enthusiastically, carefully working each syllable around her strongly foreign dialect.

Azure Spark: "No blue. Yes ult'u'ramarine! Okay?"

You nod, and ask if she knows where you can find some of this ultramarine pigment.

Azure Spark: "Yes. East'o and south'o is a swamp'u. There are many, many blueberry. Hiding'u in blueberry, you can find'o lazuberry. Looking'u very same, but the colour is more deep'u. Good for pig'u'ment'o. Okay?"

You nod, and repeat that lazuberries can be found around a swamp to the southeast, among similar-looking blueberries, and that they can be distinguished by their deeper colouring.

Azure Spark: "Yes. Al'u'so! East'o and east'o is moun'u'tain. There is a river that go into a big'u cave. You can find'o lapis'u lazuli. Very rare. But! Very good for pig'u'ment'o. Okay?"

You nod, and repeat that lapis lazuli is a valuable yet rare mineral that can be found far to the east, along a subterranean river that runs beneath the mountains.

Azure Spark: "Yes. I will make pig'u'ment'o from items'u you b'u'ring'u. You get fifty bits'u for one hoof of pig'u'ment'o. Twenty-five for half one hoof. Okay? Good luck!"

You thank Azure Spark for the information, and begin to think about which of the two materials you should go searching for.
