20w51a is the fifth snapshot for Java Edition 1.17, released on December 16, 2020, which adds axolotls, a gamerule to control when night is skipped when sleeping, makes changes to the sculk sensor, and fixes bugs.[1] This was the last snapshot released in 2020.

Additions[edit]

Items[edit]

Bucket of Axolotl
  • Obtained by right-clicking on an axolotl while holding a water bucket.
Spawn Egg
  • Added axolotl spawn eggs.

Mobs[edit]

Axolotls
  • Do not spawn naturally.
  • Are amphibious.
    • Will dry out and start taking damage after 5 minutes of being out of water.
  • Can be caught using a water bucket.
  • Are passive towards players.
  • Can be bred using tropical fish or buckets of tropical fish.
  • Come in five different colors: yellow, brown, white, pink, and blue.
    • Blue axolotls are very rare, with a 11200 chance of spawning.
  • May play dead when damaged, receiving Regeneration I.
  • Attack drowned, guardians, squid and fish.
    • Are always hostile to fish and squid, and hostile to drowned and guardians only when "tempted" by a player holding tropical fish.

Command format[edit]

/gamerule playersSleepingPercentage
  • Controls what percentage of players must sleep to skip the night.
  • When set to 0 or a negative value, a single player is sufficient to skip the night, and night is skipped immediately without the falling asleep transition.
  • When set over 100, the night cannot be skipped.
  • Set to 100 by default.
