I’ve been adding some new creatures to the game to appear in 1.24.
Here’s one of them:
It is faster and stronger than the lion, so beware! It also jumps high, will easily go over 2 blocks.
There is a secret variant of the same creature spawning rarely in snowy areas. It doesn’t have a spawn egg, like orca and some other animals, so you must search for it. I think it’s a good idea to have some animals like that – makes it worthwhile to look far and wide for the rare fauna without anticlimax of seeing someone else get the same result with cheap spawn eggs :-)
