Probably the feeling of hugging a dog or a cat, except ponies hug you back!
I wish I had a Pinkie Pie plushie D:
But I have a Twilight, I guess she works.
I don't hate her, but don't really like her either. She's just alright.
I also like her color scheme a lot too.
I don't like her because she bullies the CMC.
That's the only reason i don't like her.
