The Anden III Mount can be purchased from Edelina in Final Fantasy XIV Endwalker.

Icon	Description
	In gratitude for your kindness, the pixie Eo Tyr gifted you this peculiar ambulatory plant, which they created from the leaves of the original Anden after pruning him. While it resembles its namesake, it lacks the power of speech, and there is no telling what thoughts lie behind its permanently horrified expression.

Kind-hearted as we pixies are, we decided to turn him into a lovely leafman!

Item	Description
Anden III Horn	When blown, this sheep’s horn emits a muted (and somewhat confused) sound that brings Anden III rustling to your side.

Where To Get The Anden III Mount¶

The Anden III Mount is obtained as a reward raising Customer Satisfaction Level to 5. Before you can do the unlock the quest for Custom Deliveries you’ll need to go to (X:22.3, Y:6.8) in Mor Dhona and complete the older quest Go West, Craftsmen. Once you’ve done that, head to (X:9.3, Y:11.3) in the Crystarium and accept the quest That’s So Anden from the Supplicant Sheep. However, you’ll need a Level 80 Gatherer and Crafter before you can accept this quest.

In order to get the Customer Satisfaction Level to 5 you’ll need to complete the list of available Custom Deliveries which will change weekly. As you’re limited to the amount of Custom Deliveries you can do, getting rank 5 should take you around a month if you do all of them.
