The monster is right in the middle of the Fields. It’s a Hypoxia Zone, so make sure you have something like The Oxygen Suit equipped.

This time, your reward is a melee weapon known as the Knok Umph. This beast fights exactly like the previous ones, so keep attacking from range. Like Suburbia, it doesn’t seem like the monster will spawn unless you’re working on Moog’s side quest, so make sure you’re actively doing that. Sparkplant - You can find this Cold Zone location in the Yerpfields between the Knackyleaves and Whereabouts biomes.

For what it’s worth, we used this gun throughout most of our playthrough, so it’s worth getting quickly.

Your reward is the ranged weapon Sparkatron Hypicskromp. The first of these is the monster that holds the Suburbia vault key. As you work your way through that quest, he’ll send you out to take down monsters. To get the key, you need to either have finished or be doing Moog Munsterhunter’s side quest. The vault can be found in the northwest corner of the area inside of a tunnel guarded by a few beasts. Suburbia - This large location is found to the southwest of the Tree of Life.This haul isn’t as game-changing as others, but make sure to stay with it for some really great items. Take it down and go claim your first piece of loot. The monster should pop out to the west of the vault. North of Bricktown - Make your way north of Bricktown and eventually you’ll come across this vault.If you want some help tracking all eight of them down, check out our guide below. Either way, once you start the quest, you’ll have to fight eight massive beasts, but the rewards are certainly worth the effort.
