Usama has a passion for video games and a talent for capturing their magic in writing. He brings games to life with his words, and he's been fascinated by games for as long as he's held a joystick in his hand.

Heartopia has just introduced a new update centered around a winter theme. Alongside the new hobbies, there are also plenty of missions for players to complete. Just like many other missions in Heartopiaplayers must meet specific conditions or talk to an NPC to trigger them. One of the recently added missions requires players to locate and take photos 16 eggs in 16 dayswith only one egg available per day. This guide will walk players through the exact process of triggering the quest, as well as how to find all of these eggs daily.

This guide is a work in progress. We will continue to update it daily to include where new eggs are found.

How to get the most out of the Rainbow Event in Heartopia

The Rainbow Event in Heartopia is a limited but very rewarding opportunity. Here's how to get the most out of it.

How to unlock Onsen Egg Promise Quest in Heartopia

To unlock the Egg Hunt mission in the game, you need to talk to Erik and follow the instructions by completing the simple, straightforward tasks until you interact with Atara inside the igloo on Onsen Mountain. Once that's done, you have to find Naughty (he can be found on the ramp) and interact with him to trigger the Onsen Egg Promise quest.

You can only see and photograph one egg per day. Although there are no clear instructions on this yet, it is very likely that if you fail to complete this task on any day, you will not be able to get the grand prize.

He will explain to you that Erik plans to prepare a special winter gift for the park, and that you must get this job done. For this you 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.
