I’m asking this because I had a dream like this a few weeks ago. I can only remember bits and pieces of it but here’s what I remember:

-hyenas where added to the game, spawning in savanna biomes.

-they drop bones and hyena fur when killed and are hostile to skeletons, but will attack any mob that attacks one of them OR attacks their current prey.

-always spawns in packs (can’t remember pack size)

-hyena fur can be used to make a hyena mask which gives no armor but makes certain mobs afraid of you. (Majority of passive mobs as well as skeletons)

-there was a special variant of the mask that looked the same but was dark red, but I can’t remember what it’s purpose was.

-there was a boss that was some kind of winged hyena but I can’t remember anything else about it. The only reason I remember the wings is because it drops an item called “hyena wing fragments.” Or something like that.
