This guide will walk players through the exact process of triggering the quest, as well as how to find all of these eggs daily.
Updated February 8, 2026, by Usama Ali: The Winter event has a lot to offer for players, and there\u2019s a lot to get overwhelmed with.

We\u2019ve updated this guide to include the location for today\u2019s egg and bubble.
How to Unlock the Onsen Egg Promise Quest in Heartopia<\/p>\n

To unlock the Egg Hunt quest in the game, you need to speak to Erik and follow the instructions by completing the simple, straightforward tasks until you interact with Atara inside the igloo at Onsen Mountain. Once that\u2019s done, you need to find Naughty (he can be found on the ramp) and interact with him to trigger the Onsen Egg Promise quest.
He\u2019ll explain to you that Erik is planning to prepare a special winter gift for the park, and you need to get this job done. For this, you\u2019ll need to find 16 eggs in total to get a special reward. The only catch is that you can only find and take a picture of one egg per day.
