Humans.

Bipedal appearance, omnivore, capable of communication and (for the most part) friendly enough creatures. They are born in a specific environment that it's available for them to grow up, change - or adapt - the future of their society.

It seems that the word 'change' is not exactly what a human had in mind when finding out that he has been converted into a colored pony. How will he fare in this situation? After all, he's still human on the inside.

Right?
