How to Unlock Whack-A-Thresher Mission in Borderlands 4

Prerequisite: Complete Breeding Daisies

Before you can access the Whack-A-Thresher side mission, you must first complete the "Breeding Daisies" side quest. This mission introduces you to Mort and his unique relationship with Pandora's wildlife.

Finding Mort's Location

After completing Breeding Daisies, head to Mort's ranch located south of The Howl and west of The Launchpad. Look for the familiar wooden structures and fenced areas that characterize his property.

Slam Seven Threshers

After accepting the mission from Mort, your objective is to ground slam seven threshers that pop out of the ground around his ranch. The ground slam maneuver requires you to double jump then hold the Circle button (PlayStation) or B button (Xbox) while in the air.

Effective Strategy:

For the best vantage point, climb on top of the water tank in the center of the ranch. This elevated position gives you a clear view of the entire area, allowing you to spot threshers as soon as they emerge.

Advanced Technique:

Use your glide ability after double jumping to position yourself more accurately above the thresher markers. This allows for more responsive ground slams and reduces the chance of missing your target.
