Mojang Studios has released a public testing update for Minecraft, introducing several new features. The update includes two new cow variants: the cold cow, which has a fluffy coat suitable for cold biomes, and the auburn warm cow, found in sandy environments. New plant life includes the firefly bush, which attracts fireflies at night and thrives in swamps and near water, as well as an unassuming bush that grows in green biomes like forests and plains. The update also enhances ambient sounds in desert biomes, with players hearing whispers of sand and sounds from the dead bush, including chirping crickets and rustling twigs. Players can incorporate these sounds into their creations by placing the dead bush on sand blocks or clustering sand or terracotta blocks. These features are available in Minecraft: Java Edition through snapshots and in Minecraft: Bedrock Edition via previews/beta.
