Aprt from humans, several alien kids are attending the Fort Kerium school in the class of 2294. Fuufta and Amethystians are present as well as specimens from the species shown here. Not much is known about the large headed kid or the jumping green alien with webbed hands. The two furry bearlike aliens are brothers, leading to beleive in a familial structure similair to the human ones in this species. It is somewhat implied that all those species must have developed space travel technology for them to have come to make fortune in kerium prospecting on New Texas.
