I have a note in the journal! Please read it, thanks!

-Her horns create light and can pick up radio signals, but she admits to everyone that she reads their secret thoughts with the help of horns.
(On tail is an adornment, although perhaps they also grew there?)
-Bright white dots on her chest and ears with a strong emotional outburst begin to glow thereby comforting filly.
-She runs very fast!
-Maybe her horns are charging from the sun.

In affectionate hands at Schnilz
