B-Rad Lascelle said:You're correct. And through some astute detective work here... fans have concluded that Mosquito = Clyde, Mintberry Crunch = Kenny and Mysterion = Bradley.
In addition to the glass of water running gag, the other tipoff is that Mintberry Crunch's hair does not have Bradley's part and has Kenny's traditional darker highlights running through it.
I agree with this assertion as well. Kyle is probably not Mosquito-- he would fight back. Also, he would probably not have that fund-raising idea due to stereotypes. Kyle's lines also fit the Kite during the scene where Cartman is kicked out; the pacing and long-winded nature of his lines are testament to that.
