| _Spoiler:_ Rick lands himself in a pickle, and "lacking any
| means of mobility, he bites the head of a cockroach and walks
| upon its back by stimulating its brain with his tongue. After
| assembling more cockroaches into a crude exoskeleton, he sets up
| a lab and upgrades to a powered exoskeleton made of rat corpses."

| Fun episode!

|
| How is "necrobotics" a real field of research? :p

| microstructures. Spiders are self-assembling and made out of
| cheap materials. Anything with piloted corpses does seem a
| little fucked up. I'm creeped out imagining accidents storing
| live spiders or weird research advancements on engineered
| spiders.
