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 (and the fact that they're really just brine shrimp). 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. Pixiefrog revealed that sea simians are kept in small tank captivity, due to the fact that when released into the wild , they mutate and become feral creatures that will attack others.
