Here's a Poison Mushroom Cookie build guide, including the best Toppings, Beascuit, and team compositions in Cookie Run: Kingdom.
Poison Mushroom Cookie received their Magic Candy upgrade in Cookie Run: Kingdom. Their ability to throw a cluster of small mushrooms now includes a giant one that deals explosive damage. It’s a good ability that fits Poison-team compositions. However, it’s not a groundbreaking upgrade as there are better options in the game that require less investment.
That said, here’s our Poison Mushroom Cookie build guide and which Toppings and Beascuit we think are best to use in Cookie Run Kingdom.

Best Poison Mushroom Cookie Topping and Beascuit in CRK

Poison Mushroom Cookie in CRK is a decent DPS with supportive capabilities. Allies who are within the AoE of the mushrooms receive a DMG Reduction buff. This makes them a good unit to have if you are struggling to survive attacks from the Red Velvet Dragon Guild Boss. Unfortunately, even with their Magic Candy upgrade, Prune Juice Cookie remains the better and cheaper poison DPS to invest in for PvE content.
Toppings
- Red Velvel Dragon Build: 5x Searing Raspberry with Searing Raspberry Tart
- PvE Content: 3x Swift Chocolate + 2x Searing Raspberry with Swift Chocolate Tart
Generally, you will want to maximize the damage with Searing Raspberry toppings and tart. However, if you have the Magic Candy +20 or +30 upgrade, you can add a bit of Cooldown to spam more mushrooms.
Beascuit
- Spicy Beascuit
- Main Stats: Poison DMG
- Secondary Option: ATK, Cooldown
The Beascuit needs to have either Poison DMG, as they mainly deal elemental damage. However, rerolling for good stats can be expensive. You can settle for ATK or Coolodown until you can get more resources to reroll.
Best Poison Mushroom Cookie teams and treasures in Cookie Run Kingdom

- Guild Battle Poison Team: Black Sapphire, Candy Apple, Shadow Milk, Poison Mushroom, Pom-pom Dough
This team is cheap to build, as only Poison Mushroom Cookie has a Magic Candy upgrade. Candy Apple will provide a shield for the team to sustain. Additionally, Black Sapphire and Pom-pom Dough, despite being a support, also deal a ton of damage on top of amplifying Poison damage. Shadow Milk is there to trigger special effects from Black Sapphire and Candy Apple.
Best treasures to use

This is the our recommended treasures to use against the Red Velvet Dragon Guild Boss in CRK. As usual, equip the Jelly Watch for the Cooldown effect. Add the Crimson Magic Whistle to increase the team’s elemental damage. Lastly, get the Old Pilgrim’s Scroll to further increase the team’s ATK stat. If your team dies during the fight, consider replacing the scroll with the Disciple’s Magic Scroll, which applies less ATK buff but includes a DEF boost.
