The yellow pony from My Little Pony - Friendship is Magic.
Fluttershy is a pegasus (Has wings) and as her name describes her, she's usually timid and quiet, but she will always stand up for her friends.

She's one of the main characters of MLP, and has yellow fur, turquoise eyes and a pink tail and mane.
Her cutie mark consists of three pink butterflies with a blue body.

Fluttershy also has a passion for animals, and usually spends her time in the forest with them, but she's scared of adult dragons.

She came from Cloudsdale, a city up on the clouds above Equestria. Fluttershy wasn't as good in flying as the others, and was bullied and was called names like Klutzershy, but Rainbow Dash stood up for her.

Possibly the cutest cartoon character ever made. From the series My Little Pony: Friendship is Magic (MLP FiM) She is known for her incredible shyness, love of nature, and being the most kind, caring, thoughtful being in existence. Emotionally unstable at times, she tends to be afraid of everything, and at one point hid from her own shadow, while at other times, such as when she or her friends are endangered, goes into a rage that can make a full grown dragon cry. She also has an unnaturally strong connection with animals, and can understand them where others cannot. She had a staring contest with a cockatrice (a creature who's stare turns you to stone) and won, scaring the living hell out of it in the process. She represents the repressed person in all of us.
