The mascot of froot loops that was used by the russian branch of Kellogg's and later by their successor (and recently redesigned and replaced by boring AI slop. Ironic)

The main trigger is klgun1c0rn, additional triggers are:

• horse / horse girl / equine (using "unicorn" and "multicolored hair" can mess up hair colors, use at your own risk);

• feral / anthro / furry / furry female;

• blue horn;

• pink hooves (or add "hooves, hooved fingers" to negative prompt);

• flower in hair (or add to negative propmt);

• if you want any other emotion than happiness, you'll probably need to use higher emphasis and add "smile, happy" to negative prompt.
