This pack makes the axolotl bucket sleeping in the bucket! It'll wake up to come out of the bucket, though (This doesn't change the entity).
Now using the new item model states, the nocturnal axolotl will pop its head out for your onight adventure, go back to sleep during the day. I tried to make the animation smooth for your enjoyment. For a semblance of fairness, this only applies to the overworld, but to compensate, there is a nether-specific texture, and I do think it's better for your axolotl buddy to be alert for your most dangerous adventures.
That's all. Enjoy! =]
If you still prefer a static item (as I think it's more vanilla), or want the cycle to be shorter and independent of game time, there are downloads for that too.
Do not reupload in any capacity. If you want to use assets, ask for permission. ^-^
