Heartopia: Cooking Hobby Guide
Cooking in Heartopia is more than just making meals. When done right, it can perfectly synergize with your other hobbies.
Where to Find Butterfly Koi in Heartopia
The Butterfly Koi becomes available a little later in your fishing journey. It requires Fishing Level 5. By this point, you’ll already be familiar with fishing mechanics and have access to better tools and skills, making this catch much more manageable.
Here are the exact spawn conditions for the Butterfly Koi:
- Name: Butterfly Koi
- Location: Meadow Lake
- Time of Day: All Day
- Weather Conditions: Rainy, Rainbow
- Level Required: Level 5
The main thing to remember here is the weather. The Butterfly Koi will not appear on sunny days, no matter how long you fish. If you’re at Meadow Lake, and you don’t find the Butterfly Koi, try returning during rain or a rainbow weather event to increase your chances.
Watch your fishing line closely as it changes color from white to yellow, then red. If the line starts flashing red, briefly release the reel to reduce tension and prevent snapping.
How to Catch a Butterfly Koi in Heartopia
Catching the Butterfly Koi uses the standard fishing mechanics in Heartopia. Fishing levels increase each time you successfully catch fish, and reaching Level 5 is very achievable with consistent effort. As you level up, you’ll unlock helpful perks that make catching fish like the Butterfly Koi much easier.
Useful fishing upgrades include improved fishing rod durability, stronger fishing lines, and better chances of catching higher star-quality fish. You can also purchase special tools from Vanya, such as the Fish Attractor, which helps draw fish closer, and Mermaid Perfume, which can boost overall fishing efficiency. With the right timing, weather, and upgraded skills, the Butterfly Koi will soon be swimming straight into your collection.
