Infinity Nikki features numerous legendary creatures, some quest-related, others hidden, demanding thorough exploration. Examples include the Dawn Fox, Tulletail, Bullquet, and the Astral Swan.

Acquiring the Astral Feather from the Astral Swan is possible without the associated quest, but the quest provides valuable context. This quest is titled "Soaring Above the Starry Sky."

Soaring Above the Starry Sky Quest in Infinity Nikki

To initiate this quest, locate the Stellar Fishing Ground Peak Warp Spire and interact with Curious Pinny nearby. The quest involves visiting Lensie's house (easily found using the in-game map tracker), grooming the Astral Swan, equipping the Floral Gliding outfit, and then flying with the Swan.

Post-flight, the quest continues with these steps:

1. Return to find Pinny and Lensie.
2. Locate Elron in Stoneville.

Grooming the Astral Swan in Infinity Nikki

Grooming is simple: use the Bye-Bye Dust or a similar grooming Ability Outfit on the Astral Swan. This action also rewards you with the Astral Feather.

Equipping the Floral Gliding Outfit in Infinity Nikki

Equip the Floral Gliding Ability Outfit to enable flight. For optimal results, change to this outfit set from your wardrobe.

Flying with the Astral Swan in Infinity Nikki

Activate the Floral Gliding Ability Outfit near the Astral Swan to trigger a cutscene. Maintain proximity to the Swan throughout the flight; drifting too far will disrupt the sequence.

During the flight, press the "Soar" button when prompted. Crucially, do not deactivate the Floral Gliding outfit until the Astral Swan has completely landed. Prematurely ending the flight will prevent quest progression. A successful flight advances the quest to the next stage.
