Tiny and E.M.O.
Tiny is a custom designed and built Titan rover. She first appears, very briefly, under the direction (nominally) of Tess Fontana in "All the Rage," wreaking havoc due to a malfunction which Tess blames on Zane Donovan. She is referred to as a female. In "Momstrosity", SARAH gives all the AIs on the same level as ANDY emotions, and Tiny seems to develop a relationship with E.M.O., an emotionally capable robot created by Kevin Blake for a homework assignment. Unfortunately, Zane Donovan disables these emotions in everyone but ANDY.
Tiny was sent to Titan to collect samples for testing. Upon return, she blew up because her samples were too large and became unstable, and caused sinkholes that threatened to destroy Eureka. This was prevented by Holly Marten and Douglas Fargo.
