Flower Creepers are annoying, stealthy, and a common sight to many new players. Their behavior towards other hostile mobs can sometimes put up quite a show. Their range of sight is doubled and will be able to see entities within a 32-block range.
Flower Creepers are very small and only reach up to 1/4 the height of a block. They sneak up on unsuspecting players and explode. Despite their size, the explosion caused by a Flower Creeper is about 1.5x larger than a normal creeper's. They make absolutely no sound, even when hit or about to detonate.
Flower Creepers are commonly found in grassy areas with a light level of at least 11 or higher, including the Plains biome. Where there are roses, there are likely to be Flower Creepers.
