The Earth Monsters are a group of Tower Attacks which summon XANA's Monsters on Earth and will replace every destroyed monster every 3 minutes.
There exists one Earth Monsters attack per available monster type and therefore it is impossible for different types of monsters to be materialized at the same time. All the possible types are: Kankrelats, Bloks, Hornets, Krabs, Mantas and Megatanks. The player count requirements for each Earth Monster attack depends on the monster type that will be summoned.
These attacks launch as many Monster Spawner processes within the activated Tower as monsters materialized on Earth.
