Fuzosheppu

The Fuzosheppu, or Oogasumi (as named by Riko), is a hive creature which makes its appearance in The Village of Iruburu.

Description
The Fuzosheppu is an enormous creature. It has a head similar to that of a crustacean's and a mostly amorphous, gelatinous body with visible internal organs, such as its Force Field-sensing organ. It can fly outside of the Force Field, presumably being lighter than air.

Riko speculates that Fuzosheppu don't hunt in packs, are aggressive, agile, and stubborn. Wazukyan elaborates on the creature, explaining that a Fuzosheppu is not a singular creature, but a hive of them. They form a nest consisting of transparent males and a visible "queen", which resembles the head. After a nest's queen dies, the males will leave in search of a new one, with one of the males growing to become a new queen.

Trivia

 * Though lightweight, these hive creatures can even hold its own against enormous individuals, if they fasten themself to a surface.
