She is obedient but somewhat absent-minded, such as when she forgot to give Sprout the step for his pedestal. She is also shown to enjoy bubblegum and can be seen blowing bubbles in a couple of scenes.
After previously fearing unicorns and pegasi, Sweets now accepts friendship between all three pony kinds.
She is a taffy pink earth pony with lighter fetlocks, slightly darker eyebrows, and mauve hooves. She has a raspberry pink mane and tail with light pink streaks. Her mane is tied back with the ponytail pointing upwards, and she has a straight fringe. Her eyes are emerald green.
She wears a white collar with a green tie, and a green ID holder clipped to it. She has a hair accessory around her tail, close to the tip.
In early concept arts of the movie, Sweets' color palette was similar to Hitch Trailblazer's, with a yellow streak on her mane.
