Jack is Nibbler's brother. I know, I know. It's easier to comprehend if you think of yin and yang. They balance each other out. Jack follows his brother around and is very picky about his goat yoga companion. He is a very smart and fun goatie, he just isn't about to show just anyone his true self. He takes a while to get comfortable with new people.
Laying in the sun, Nirvana, and poetry.
Being dressed up, being brushed, conforming to societal expectations, talking about his past goat yoga girls.
