The Floater is a flying insect-like monster that can abduct and consume up to three townspeople. Unlike the standard Greedling units that are usually killed in one hit, Floaters require more shots from Archers before dying. They first appear during the third Blood Moon, but they become more common as days pass, taking part in the usual nightly raids. Their goal is not so much to take the Kingdom's stuff, but to take its people. Floaters sometimes dive to attack the Monarch, forcing coins to drop on hit.
Floaters ignore dropped coins and tools, with their only purpose being to abduct and kill the Kingdom's townsfolk. Floaters fly slowly towards the center of the Kingdom until they target a townsperson, then they swoop low to gather them up then return to floating towards the center of the Kingdom. Once three villagers are captured, a Floater turns back towards the nearest Portal to disappear with its prisoners.
Abducted townspeople can be freed if the Floaters is killed within a few seconds of consumption. For a few moments, they'll lie prone in a heap, but then resume normal activity after a few seconds. Also note that when townspeople are captured by Floaters, both their tool and their coin are consumed as well.
Floaters, like Breeders, ignore the return of the day and will continue to attack until all of them are dead or filled, creating trains of Floaters extending for a good part of the day in Winter, preventing any unit to leave the walls of the Kingdom.
The best protection against floaters is catapults, ballistas, or heavy arrow fire. Catapults and ballistas always kill Floaters with a single shot, which makes them useful against these creatures if their shots can be timed right. Archers perched in fully-upgraded Archer Towers also serve to protect ground troops from Floater attacks, as Floaters prioritize abducting Archers posted to towers. As with other enemies, having as many archers as possible helps to minimize the damage done by Floaters during an attack.
