People asked what the Breezies from MLP would look like as Tiny Sapient Ungulates, so here’s some magic flying horse mice?
 
If ponies are like grey aliens compared to real horses, Breezies are grey aliens compared to ponies. Their wings are a magic construct to help them float… sorta like a regular pegasus’s wings, but without the meat around them. They’re from a dimension with a much higher magic saturation than the MLPverse and are extremely dependent on magic for their regular function. The eight long antenna on their heads serve as conductors for ambient magic, if you snipped them off all at once they would no longer be able to maintain their wings and probably suffer some significant health problems. The antenna are stiff but flexible, comparable in texture to scales or thin fingernails.
