It is snapshot day my dudes, welcome to the first Minecraft 1.17 Caves & Cliffs snapshot of 2021. Today we have the very controversial Glow Squid mob and a new feature called “Glow Lichen” below are all the details you need to know, check your Minecraft launcher for 21W03A.


A Minecraft Java Snapshot

Today’s Caves & Cliffs snapshot is particularly shiny! You could almost say it’s glowing… Oh wait, that’s a squid.


  • Added glow lichen!
  • Added glow squid!


  • A dim light source that generates in caves.
  • Use shears to pick it up.
  • Use bonemeal to spread it along block surfaces.


Glow squids have been added, but do not yet spawn naturally. You can find spawn eggs for them in the creative inventory.

  • Glow Squids are well-lit and can be seen from even far distances!
  • When killed, glow squids drop glow ink sacs.
  • Glow ink sacs can be used on signs to make the text super visible, even at night! Works with colors!
  • Craft a glow item frame by combining a glow ink sac with an item frame in a crafting table. Any item in a glow item frame is perfectly illuminated, even at night!
  • Use an Ink Sac on a sign to remove the glow effect.
  • Axolotls will attack any glow squids they see, so…be careful.


  • Dripstone blocks can be crafted from 4 pointed dripstone.
