2025's first Minecraft game update is shaping up to be an exciting one for fans of mobs and ambiance. In a previous snapshot, Mojang unveiled new pig variants and introduced beautiful ambiance blocks throughout the Overworld. In the latest Minecraft snapshot, 25w05a, Mojang has taken things to the next level by adding two new cow variants and fireflies.Many fans might remember how Mojang announced fireflies for The Wild Update but later canceled them. This creature has now returned as a block called the firefly bush instead of as a mob. Instead of being a tiny two-pixel mob, Mojang has turned fireflies into a block effect for the new firefly bush.Like pigs, cows now have temperate, warm, and cold variants in Minecraft. Along with the new cow variants, Mojang has also updated the existing cow model. Other exciting features include new desert ambient sounds, beacon improvements, and various bug fixes.Here are the patch notes for the latest Minecraft snapshot 25w05a.Minecraft snapshot 25w05a patch notes: All you need to knowAdded cold and warm variants for the CowAdded Firefly Bush blockAdded Bush blockAdded new ambient block sounds for ambient sounds in Desert and Badlands biomesCow VariantsCow variants (Image via Mojang)New Cow variants have been added, the variant is determined by the biome they spawn inTemperate variant -
