Bunch of Ice Holes

Bunch of Ice Holes is an optional quest in Borderlands: The Pre-Sequel given by Nurse Nina. She will ask the vault hunters to pick up her drill and take it to a cave marked on the vault hunters map. Once there she will direct the vault hunters to place the drill in the first location in an ice pool (beware the ice pools will do damage over time if the vault hunters stand in them). Once the drill is placed creatures will spawn and the vault hunters will have to kill them to progress. Repeat two more times then return to Concordia for the vault hunters reward. Turning the quest into B4R-BOT yields Too Scoops a blue quality shotgun, while turning it into Nina will yield Ice Scream a blue quality assault rifle.
