Cerebro-slug
In the second episode, Brennan lists Cerebro-slugs among possible explanations for the Skipper's behaviour, alongside a change of heart, psychic influence and tractor beams, and adds that it could be anything SOE2·00:37:21.
Cerebro-slugs are slugs that take over bodies, and a tour guide at Fantanimalland calls them an extremely invasive species SOE11·00:21:31 SOE14·01:42:10. In the third episode Brennan recaps that some kind of Cerebro-slug has blasted its way into the brain stem of the captain, Norman "The Skipper" Takamori SOE3·00:00:52. In the fourth episode Melon addresses Skip as Prince Valdrinor, with character art of a green Cerebro-slug, and mentions his father, King Prilbus SOE4·02:45:03 SOE4·02:45:20. After a pug licks his eye, Brennan tells Skip he immediately thought the pug is a superior and its owner is probably another Cerebro-slug SOE4·02:49:51.
Brennan explains how they live: after about three days in a body is the hump, and they succeed as a species by convincingly being the person SOE6·00:31:33. In slug form they sense only nearby intelligences SOE6·00:20:26, and they are fluid and adopt the gender of the body they are in SOE7·00:47:48. Skip tells the crew he is "royalty among the slugs" and speaks of the Great Emhatchening SOE12·00:18:45, which Brennan says needs all the great lines and noble houses present SOE12·00:21:04.
Brennan says Cerebro-slugs latch onto the brain stem, kill the host and lay the eggs SOE14·01:42:10. King Prilbus shows Skip how they breed by taking over the base of the brain stem SOE15·00:44:55. When Skip rides on a hand as a slug, Brennan says he has no eyes or ears and senses a mind as psychic warmth SOE16·00:06:18 SOE16·00:24:50. In the seventeenth episode Barry Syx says "Barry slug" while the crew sort out which Barry they mean SOE17·00:18:05. He then apologizes to King Prilbus, and Skip says "Father" SOE17·00:18:07 SOE17·00:18:14.
In the finale Skip fights his father Prilbus for control of a host, takes over Loose Duke, sneezes Prilbus out, shoots him SOE18·01:55:58 SOE18·01:56:44. Skip then says, "The king is dead. Long live the king." SOE18·01:57:04. Gnosis then shows Skip many other Cerebro-slug communities that could live alongside their hosts SOE18·02:53:16.
