Queenigma is a bounty plant in Plants vs. Zombies: Battle for Neighborville. She resembles a Rose wearing the Fairy Queen costume. She can be hunted in the Weirding Woods near the starting point. Defeating her unlocks the Diss from a Rose medal.
Her name is a portmanteau of the words, "queen" and "enigma."
Queenigma is invincible when the spawned mushrooms are still present, as hinted by the "halt truffle kerfuffle" objective. Use the Super Brainz to take them down quickly. The Night Caps can be nearly killed in one hit by using a fully charged fist, preventing her from turning invincible. Once they are taken care of, you have 20 seconds to defeat her before she turns invincible again, spawning even more mushrooms, so just attack her quickly with the fists until she is defeated. Don't use Electric Slide's Funky Bouncer ability; while this might be a good idea due to the fact that there's a lake nearby to drown her into, she can't be pushed away by the magnet unlike normal Roses.
All-Star is also another good choice, considering how his dummy shield can protect you from the Night Caps as you safely kill them one by one. Sprint Tackle can also one shot individual Night Caps if it lands accurately, although be careful not to overheat your primary weapon during Queenigma's vulnerability.
- Prior to the October 2019 patch, you could bypass the requirement to defeat the mushrooms first by using Electric Slide and push her into the lake with the Funky Bouncer, in which it was the fastest way to farm XP, coins, and tacos, but this was later nerfed in an unlisted change so that she can't be pushed away by the magnet. The November 2019 patch made farming even more inefficient by reducing the yield of the XP and coins as well as removing the 10 marshmallows bonus after defeating her. As of the December 2019 patch, bounty hunt farming has been effectively disabled due to an addition of 15 second cooldown after each bounty hunt attempts.
