The Reindeer Boss was a boss added in the December 25th, 2020 update. Upon defeat, players could choose either Sleigher or the Shredder as their reward. If a player defeated it a second time, they would respawn and receive the alternative vehicle. The boss event was removed on February 4th, 2021.

Initiating the Fight

Main article: Generator Battery

Batteries can be found in preset locations on the shorelines throughout the map. They are used to restore 50 power to the generator in Easter Isle, which, upon reaching 500 power, will unlock the event. A purple circle near the generator can be stood upon to activate a countdown, which, upon reaching zero, will teleport a maximum of ten players standing on it to the event.

Before the boss fight takes place, players are tasked with scaling a wintery mountain that is littered with Elf Cores which spawn evil elves until they are taken down. Many areas of the mountain appear to be plagued with the same purple corruption that is currently overtaking part of the city.

Once all surviving players ascend to the summit and reach a cage, they will be met by Defaultos, who reveals their plan to to take over Roblox (starting with Mad City) and then the world. Defaultos claims it is not yet time for the player and them to fight, before transforming the reindeer into a mutant, initiating the final battle.


The Reindeer Boss has five attacks that are chosen at random, and are listed below:

  • Bite - The Reindeer Boss chomps at the air, summoning flying teeth that lock onto players. If a player makes a set of teeth touch the Reindeer Boss, they will be stunned, becoming vulnerable for the players' attacks.
  • Earthquake - The Reindeer Boss creates two shockwaves that damage players.
  • Tornados - The Reindeer Boss will summon tornados that deal damage and trip players.
  • Reindeer Blaster - Two reindeer heads will appear consecutively, spawning and targeting a single player before playing an audio cue and firing a laser at them from their mouths.
  • Elf Core Regeneration - This attack respawns any elf cores that were destroyed and is passively used after a few seconds of an elf core being destroyed.
