Hammerlock wants to come up with a better name for the Bullymongs, so he sends you out to search their bone piles so he can learn some things about them. Note that you can go anywhere there’s Bullymongs, so you’re not restricted to the location the waypoint is sending you. There’s also an optional objective here to kill 15 Bullymongs. The bone piles are the ice things you can break in the frozen areas.

With that done, their new names are now Primal Beasts and Hammerlock says to blow them up with grenades. You only need to kill one with a grenade and after you’re done, their new name will be Ferovores. Your new task is to shoot three of their projectiles out of the air. If you’ve been paying attention to the enemies you’ve been fighting, then you know that Slingers will always sit back and toss rocks at you (the others do it less frequently, if at all).

Bullymong Slingers will sit back and toss rocks at you, so they are ideal for the third objective.

Something like a shotgun or pistol will make it easier to shoot the rocks while they are in the air. Once you’re finished with that, Hammerlock will make one last change to their names. They will all now be known as Bonerfarts…yes, Bonerfarts. Just kill five of them to finish up, then return to Hammerlock to get your reward.
