The "Flask Robonoids" are spherical robots that first appeared in "Warp Tour." They assist Peridot, but receive no kindness from her in return. They also appeared in the episodes "On the Run" and "Political Power", having been gathered by the Crystal Gems to prevent them from reactivating and fixing the homeworld warp.
Flask Robonoids are light green orbs with four cylindrical legs. They can launch a teal liquid that is used to repair Warp Pads.
Plug Robonoids are a larger variant of the Flash Robonoids, who debuted in the episode "Marble Madness". They have seven conical legs instead of four cylindrical ones, and appear more transparent than their smaller counterparts
A flask robonoid's function is to repair warp pads using a special liquid that they squirt through a small, concealed nozzle. Flask Robonoids can also double as Peridot's hand print signature in her absence.
