some of these are pretty funny. troy girls are currently two mongolians. not included in the list are de:va who consist of a french-senegalese, a swiss, an armenian, and an australian of liberian-nigerian-sierra leonian descent who sadly already lost a columbian, a japanese, and a filipino-saudian (lmao) member.

among the more interesting debuts are 4iren and newy (four former i-land 2 contestants) i think.
