Nubs

Nubs is one half of the Chubs 'n' Nubs duo boss fight, the final boss encounter of The Junkyard in Act 1. Like her partner Chubs, Nubs is a blind, headless dog whose movement and attacks are randomized due to her inability to see. The unpredictable nature of both dogs fighting simultaneously makes this one of the more chaotic early-game boss encounters.

Nubs's specific combat abilities include lobbing a Creep shot when damaged and performing a leap attack with knockback. The Creep shot creates hazardous terrain on the battlefield, progressively limiting safe space as the fight continues. Her leap attack can displace cats from their positions, potentially knocking them into Creep tiles or into Chubs's attack range. When Chubs is killed first, Nubs enrages for the remainder of the battle with significantly enhanced attack properties.

Avoid standing on Creep tiles created by Nubs's reactive shots, and maintain awareness of the growing hazard zones on the battlefield. Balance damage between both dogs to minimize enrage time. Nubs's leap attack can be particularly dangerous when it knocks a cat toward Chubs's position, so keeping space between both bosses reduces the chance of chain displacement damage. Focus fire on whichever dog you want to kill second when both are low, and finish the remaining one quickly.
