The same just happened with axolotls on seed 7394224640132927697 on a flat world in 21w15a
at coordanates -811.424, 6.20000, 661.063
Axolotls have simalar spawning patterns as well
It looks like this bug still affects the latest snapshot 21w14a
It turns out this glitch only works in 21w08b. However, if a world from that snapshot with a fire sky is loaded, the fire is still floating.
I decided to check, this glitch no longer works.
On the second file, the hitbox of the dog is shown making it eaisier to see the glitch/bug
Maybe the bug was resolved while I was playing mc, and I coundn't get it to work again. ¯_(ツ)_/¯
true
I am not sure what the minimum or maximum axolotls there can be in one village well, but from my experience, I found two axolotls, one lucy color, and one cyan. (names found from here https://minecraft.fandom.com/wiki/Axolotl)
