Sprite bots are automated mechanical flying drones patrolling the Equestrian Wasteland. They were deployed by the Ministry of Morale to spread uplifting music throughout the land, and still continue to diligently annoy all wastelanders with their repeating polka music. They notably play March of the Parasprites. However, behind the innocent cover of spreading music, the actual purpose of the drones was to act as a country-wide surveillance and counter-espionage network, with each drone serving as independent network node.
The sprite-bot consists of a round metal body the size of a foal's head, with four mechanical wings attached to it. It has a magic class laser weapon built into it, for defending itself against enemies.
Sprite bots that have been in contact with pink cloud/ taint have been corrupted and their music is fatal to living creatures within close enough proximity to them. The only creatures able to withstand the corrupted affect is Canterlot Ghouls, which have been transformed similarly by pink cloud/ taint.
