I've now decided they're definately going to be Tic, Tac and Toe.
Tic and Tac are the white ones, because of the little minty sweets "Tic Tacs"..
Tic is the one with the light nose
Tac is the one with the darker nose
Toe is the brown one
It's soo hard to tell the white ones apart, I can only tell when I get a good view of their face ::)
