A green creature on four legs. A kamikaze mob that sneaks up on a careless player and explodes, damaging not only the target, but also terrain and buildings within a radius of 3-5 blocks.
A creeper can become charged if lightning strikes within a 4 block radius or an easter egg is used. A charged creeper does tremendous damage to living creatures and the area, damaging blocks even behind water barriers.
The creeper is the main "weapon" in the griffin, as it is capable of blowing up crates and chests in other people's zones. That said, the creeper is most often cast with a fishing rod or carried in a wagon, thus bypassing most of the obstacles. For those who want a safe game, special features on the planets Farm, Prometeus, Laboratory were included - disabling damage from creepers and players in their zone.
