The Arnold 3000 is a Legendary Pet introduced in the 11.3.0 update.


It looks similar to the Dog, albeit with darker fur, most likely burnt, and instead of its right eye being normal, it has a mechanically implemented robot eye to it along with a robotic body and robotic wrists and ankles.


A level 1 Arnold 3000 deals a decent amount of damage, has a good health, a good speed and a somewhat short respawn time.


  • The Arnold 3000 deals terrifyingly high damage to armor-less or low level players making it a great starter pet.
  • Since the Arnold 3000 is a Legendary pet you can use it to surprise unsuspecting enemies.
  • If you're a sniper, get this pet with strong armor so players behind you would be killed by the Arnold 3000.
    • Your Arnold 3000 teleports to you when you are far away so you don't have to worry about it getting "lost" when you rocket jump.


  • It has low health meaning that it can be exterminated in around 2-5 shots from a Primary weapon.
  • Kill it when using weapons with a high fire rate and great accuracy, such as the Crystal Laser Cannon.
