The "Flask Robonoids" are spherical robots that first appeared in "Warp Tour". They assist Peridot, but receive no kindness in return. They also appeared in the episode "On the Run", having been gathered by the Crystal Gems to prevent them from reactivating and fixing the homeworld warp.
Flask Robonoids are teal/blue orbs that can protrude four cylindrical extensions that act as legs. They have a small blaster that launches a teal warp pad repairing liquid.
Plug Robonoids are a noticeably larger variant, around 1.5x taller than Garnet. They have seven conical legs instead of four cylindrical ones. They appear more transparent than the smaller ones. They also can also change their shape at will.
A flask robonoid's function is to repair warp pads using a special liquid that they squirt through a small, concealed nozzle. This liquid can be used to attack enemies. They can also compensate for lost legs. Flask Robonoids can also double as Peridot's hand print signature in her absence.
- They are hard enough to produce a crack in a warp pad, but soft enough to be squashed by Peridot and Amethyst, however, that is most likely just a result of their strength.
- They seem to have a certain amount of emotion, but seem to remain completely stoic until they are damaged in any way.
- They appear to run on an internal power source that can be disabled by Peridot's EMP.
- The much larger version of them called "Plug Robonoids" first appeared on the episode "Marble Madness".
