"Solaricks" is the premiere episode of the sixth season of the Adult Swim animated television series Rick and Morty.
Rick gathers materials he needs from his old house while conversing with D.I.A.N.E., an AI of his deceased wife Diane Sanchez he once created to "haunt" him.
In the Cronenberged dimension, Morty encounters his Jerry, who travels by himself after the deaths of his Beth and Summer[d] and has adopted a Rick-like nihilistic philosophy.
The family returns to Dimension C-131, where they encounter the "Season Two" Jerry who was brought back to the house and has been taking a shower upstairs while waiting for them to sort everything out.
However, he accidentally unleashes a cute but deadly parasitic creature named Mr. Frundles that takes over and destroys the world in a mere 30 seconds, forcing the entire family plus Space Beth to move to yet another replacement dimension, where they coincidentally died at the exact moment of "natural" causes – the only major difference being that residents of this dimension pronounce "parmesan" strangely.
