The Jelliens are simply pink jellyfish, with big, glossy, Jellien eyes. However, despite their very innocent and cute appearance, and how they don't zap people much, they are able to absorb their prey, before putting them into a membrane-like prison for their overlord. Doing so, also causes them to create an almost identical copy of their prey, with the only difference being that they're expressionless, and have glossy eyes as well. They try to befriend and stalk prey, using their innocence.
