Heartopia has just introduced a new update centered around a winter theme. Alongside the new hobbies, there are also plenty of quests for players to complete. Just like many other quests in Heartopia, players have to meet specific conditions or talk to an NPC to trigger them. One of the newly added quests requires players to locate and take photos of 16 eggs over 16 days, with 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’ll continue updating it daily to include the locations of new eggs.
How to Make the Most of the Rainbow Event in Heartopia
The Rainbow Event in Heartopia is a limited but highly rewarding opportunity. Here’s how to make the most of it.
How to Unlock the Onsen Egg Promise Quest in Heartopia
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’s done, you need to find Naughty (he can be found on the ramp) and interact with him to trigger the Onsen Egg Promise quest.
You can only spot and photograph one egg per day. While there are no clear instructions about this yet, it’s highly likely that if you fail to complete this task on any day, you won’t be able to get the grand prize.
He’ll 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’ll 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.
All Onsen Egg Locations in Heartopia
In addition to finding an egg, you can also find and burst a furniture bubble to get a special furniture item that can be placed in your home. The table below showcases the locations of all eggs and bubbles you can find during this event in Heartopia:
