Sea Simian Can
The Sea Simians are pet sea-monkeys that Jake Spidermonkey bought in "Synch or Swim".


In "Synch or Swim", Jake was banned from joining the CDMS Swim Team due to him not being an aquatic animal. So, he bought a bunch of sea simians online, to prove that monkeys could be aquatic animals, not understanding that "sea simian" was just an artifact title. When he bought the sea monkeys, he was dazzled by them, but they were invisible to everyone else. After 4 to 6 seconds of owning them, he quickly got bored of them and flushed them down the toilet, which caused them to mutate into horrible monsters.
