Bluecow

Note that this does not exist in Minecraft; it was written purely as a fiction article.

Bluecows are strange, mutated versions of cows found specially in Bluehigh. They have the same cow pattern, but are red and blue with two tails. They make down-pitched cow sounds.

Behavior
Bluecows tend to cluster together and will flee from any mob within 16 blocks, except their own species. When hit, they make a Zombie Pigman's hurt sound. They cannot swim and will avoid water and lava if they can. They ignore fall damage and can fall off cliffs when running away and kill themselves.

Habitat
Bluecows are found only in the parallel dimension Bluehigh, being seen in very large groups of sometimes up to 30. They naturally spawn near mountains.
