Confirmed on XBOX 1.
i mean too
This also occurs when you get to far away, and the open mouth stays until you get close enough for it to shoot.
Same with me on XBOX 1, sometimes if you crit or have sharpness it still splays the particles but doesn’t deal damage. This is easiest to see with the ender dragon. Still happens on 1.21.111.
I can confirm on XBOX 1. I always thought this was an intended feature. There was also a glitch were the natural world gen would override the main hall and remove the blocks. There is also an old glitch from when they were first implemented where glow lichen could be generated floating without breaking. You can collect it with shears and it behaves as normal.
Does this affect other mobs as well?
