Heartopia is a cozy life simulator full of exploration, hobbies, and exciting seasonal events. One of the most valuable events in the game is the Rainbow Event. This rare, limited-time event appears periodically. It rewards exclusive items and powerful boosts, but lasts only a few real-world hours. If you want to be prepared to make the most of the Rainbow Event in Heartopia, this guide will tell you everything you need to know.
How the Rainbow Event works in Heartopia

You can check if the event is active by opening the in-game Clock. A rainbow icon indicates that the event has started and displays upcoming Rainbow Days. It only triggers under certain weather conditions.
While the event is active, players receive special boosts and a chance to collect exclusive items not available during regular events. Here are some of the benefits of Rainbow Events in Heartopia:
Location of the special Rainbow Trader Doris

Doris is a wandering NPC who appears during the Rainbow Event. On normal rainy days, she can be found in specific locations around town, but during the event, we spotted her at Mount Onsen or near the bridge to Forest Island .
Doris’s shop offers a variety of limited-time items. These include colored sugars like Yellow and Indigo, which are used in special Rainbow Roll recipes, and a unique Rainbow Emote for 2,000 coins. She also sells postcards. Collecting these items is recommended, as she only appears during the event. Be sure to stock up on sugar , as it can only be purchased from Doris.
Rainbow Bouquet Locations
Another key feature of the event is Rainbow Bouquets . During the event, you can collect three floating rainbow bouquets. Each one resembles a rainbow-colored four-leaf clover.
The Rainbow Bouquet provides a 30-minute boost. When activated, you and nearby participants receive a 30-minute blessing that improves the star rating (rarity) of Fishing, Cooking, Bug Catching, and other hobbies.
Watering plants at this time can also release Rainbow Pollen to improve breeding results.
Three bouquets can be found in the following locations:
- Outside your home.
- On Mount Onsen, on top of a cliff that you can climb.
- On Mount Onsen (elsewhere).
Plan your activities around these buffs to get the most out of them. These buffs can also be combined with other food-related buffs.
How to Make the Most of the Rainbow Event in Heartopia

The Rainbow Event is one of the best opportunities for efficient resource gathering . Ancient Trees located in the four corners of the main city drop rare wood. Thanks to the Rainbow Bouquet boost, the amount of this wood even doubles during the event.
Gathering resources such as ore stones, berry bushes, and Black Truffles is more profitable than usual during the Rainbow Event. This makes it an ideal time to gather materials needed for crafting or cooking. Black Truffles are especially valuable. They can be gathered in the Forest Island area and are used in recipes like Truffle Pies, which sell well.
Rainbow days also increase the spawn rate of certain rare fish, such as the Butterfly Koi in Meadow Lake .
