This area is another that doesn’t have a pastword/Tockle attached to it, as you need to finish another area in order to unlock it. Simply finish Roamer Encampment and you will automatically receive the unlock from Rom Baro upon getting your reward.
Speak to Lala, who is the female NPC in front of the main tent, next to Rom Baro and Kiefer. The Roamers are set to do their dance, but their Torban of Truth is broken, so she wants your help in repairing it. You will receive the No Music, No Life quest here, but in order to finish it, you will need access to the Pillar of Pegasus area, so you might need to wait a little bit until you unlock that. In particular, you need to find a specific enemy inside of the Pillar of Pegasus.
The enemy you’re looking for is called Hot Dog, which is found throughout the dungeon and isn’t all too uncommon. It is highly likely you will run into some while making the trek through the place normally. Anyway, all you need to do is defeat a single Hot Dog and you will get the golden mane to drop after that battle. Once you have that item, bring it back to Lala in Roamer Encampment (Night) to finish the quest, with your reward being a pair of Elevating Shoes.
