I WANT TO EAT IT
So everyone wants more love given to wolves with different types. I find this dumb. Cats can be almost copy paste to be changed. But dogs have different sizes and shapes. And finding dogs in the wild seems wrong, but more then 1 unique type of pet in villages also seems wrong. But what if wolves... Varried.
So what do I mean? What if wolves spawned with different colors other then light gray. Maybe black? Tan? White? Dark gray? Simple changes can help players get even MORE attached.
Actually why stop their? Different white patches on cows. Muddy pigs. Different chickens. Brown bears. Various snow golems faces. Horned sheep. Flower mooshrooms. IDEAS ARE ENDLESS!
So, most ideas go along the lines of ''tHiS wOUld be CoOl'' but here is an actual idea.
So Owls. I think owls would be an enemy during the night and neutral during the day. And during the night they would attack. Not the player, but they're pets. Everyone is deathly connected to their dogs and cats. So at night while being surrounded by zombies, you hear quick swoosh and a hurt sound, just to look up and see an owl about to drop your beloved friend. Better go catch him/her and fight that owl away!
I think they would spawn in snowy spruce(white colored) and forests(brown). Maybe they would occasionally catch a rabbit. And my favorite thing of all, the Who?'s ringing from the forest.
I think this is a great idea, fits all criteria. Interesting gameplay. Cool new animal. And helps the forest seem more scary/real.
