Legend of Mushroom is one of the most successful idle mobile RPGs, and this isn’t its first collaboration: previously, it partnered with Alliance of Guardians to host a limited-time event that garnered significant attention. This time, it is One Punch IP’s turn: for a short period, you can obtain new heroes, outfits, and pets simply by logging into the game. Let’s take a closer look at the event’s content and the rewards you can earn.

Legend of Mushroom x One Punch collaboration period

This event started on November 27, 2025 and will last for at least 14 days. There is no officially announced end date, but since you can collect all the gifts within 14 days, we can say it’s a two-week collaboration. To speed up the process, you can use the following code, which is valid during the same time period: HERO.

Legend of Mushroom x One Punch collaboration rewards

The rewards you can collect during this event include:

• Special outfit: Saitama – Casual
• Exclusive pet: Genos
• Star heroes: King and Hellish Blizzard
• Accessory: Mumen Rider
• Exclusive Avatar Frame

This collaboration is designed as part of the Legend of Mushroom’s “Heroic Journey” event, and you need to log into the game every day for 14 days to collect the rewards. You will also be able to try out a new game mode called “Mosquito Buster”: this is a mode where you try to swat mosquitoes attacking a cactus, and the more mosquitoes you hit before time runs out, the higher your score will be. The content of the rewards you receive is also determined by this score.

You can access the event rewards (and the goals you need to complete) from the right side of the main game interface. As always, don’t forget to play Legend of Mushroom on PC with BlueStacks: With our Macro Recorder feature, you can take the game’s idle mechanics one step further and complete collaborative activities much faster!
