S1·E28 Dirty Work

Cosmo gets K-3000 Uni-appliance for Cosmo's Diner (the diner that Team Lightyear seems to spend too much time at); the K-3000 Uni-appliance is an experimental device that absorbs one's kitchen appliances into itself, and is able to use them all due to its powerful, experimental energy source and its ""liquid steel"" structure (...possibly constructed of nanobots?...very much like a robotic shoggoth, from H.P.Lovecraft's stories...). NOS-4-A2 senses the power within the K-3000 when the Courier delivering it passes close to the abandoned ship that he was residing in, trails after it, and takes control of the K-3000, all of Cosmo's restaurant equipment, and then all of Cosmo's Diner. Team Lightyear is in the process of returning Professor Triffid to his home planet, Rhizome, after a failed attempt on his part to convince Star Command to incorporate ""organic vegegenetic technology"" into their systems, when they receive the distress call from Cosmo.
