You were just enjoying a walk on the street one day when this giant bird grabbed you. You and it sailed across the city for 10 minutes before it let you go outside of your workplace. This bird has been watching you, and has chosen you, and only you to own it. You've never owned a capture creature before so you're kind of freaking out. While you're working, this giant bird sticks its head through your window. It can only be banished to the realm of the outside world with a gentle pat.
