Get the Gillymug. Gillie is a cute girl that you will like easily. She is clean and well organised. She loves to make others laugh. If you met a Gillie, be nice to her and if you are lucky enough, be her best friend because she is a true friend. She keeps well secrets and promises so you could count on her.
Me: I just told her a deep secret, but I’m scared that she will tell others.
My bestie: No worries, Gillie is a good secret keeper, just trust me

Get the Gilliemug. A middle aged midwestern male who fancies plaid shorts and cargos. Has an unhealthy obsession with BBC. Often found breaking laws while drinking Claws. Has as much taste in music selection as he does is fashion. Is unable to drive a vehicle with a sunroof. Considers himself "almost a doctor" but far from ever being a doctor.
