Snapshot Overview 25w05a for Minecraft 1.21.5

This snapshot updates the model of regular cows found in temperate biomes. The texture has been improved: spots are more vibrant, and the snout has gained a more 3D appearance. Mooshrooms (both red and brown) remain unchanged and keep their flat model.

Two additional cow variants have been introduced, differing based on their habitat:

• Snowy Cow (Cold Variant) – inhabits cold biomes such as snowy taigas, spruce and pine podzol forests, as well as highlands with weathered blocks. It has a thick woolly coat and a new 3D snout model.

• Tropical Cow (Warm Variant) – found in hot biomes such as savannas, savanna plateaus, jungles (including bamboo forests), and badlands. It features a solid-colored coat and large horns. Calves inherit the characteristic horns of adult cows.

Breeding different types of cows results in a random calf variant, inheriting physical traits from one of the parents.

A new decorative block resembling grass but with unique properties:

• Spawns in plains, forests, near rivers, and some other biomes.

• Can be harvested by breaking it, does not require silk touch.

• Used in composters but cannot be crafted into dyes or placed in flower pots.

• Spreads when bone meal is applied, similar to moss.

Fireflies, previously announced but not added in the official release, now appear as a bush:

• At night, glowing particles appear within the bush.

• Spawns in swamps and near rivers.

• When broken, the firefly animation persists.

• Can be spread using bone meal.

• Particles are not visible during the day, but the block remains illuminated.

• In dark areas, the animation appears even in daylight.

• Emits a low level of light and is not used in crafting.

• Increased visibility range of the beam both vertically and horizontally.

• The beam is now visible up to 2048 blocks in height.

• Remains visible over greater distances in horizontal render settings, making navigation easier.

• Unique ambient sounds added for deserts and badlands.

• Sand, red sand, dead bushes, and terracotta now have distinct sound effects similar to forest biomes.

• Adjusted mechanics for wearing leather boots.

• Falling from a height of two blocks no longer causes sinking.

• Falling from three blocks or higher causes the player to sink into powder snow.

Snapshot 25w05a showcases changes in the game's visual aspects and certain gameplay mechanics. The introduction of new cow variants, decorative bushes, and animated fireflies makes the world feel more alive.
