The Monster Trainer walks in with a backpack slung over one shoulder and a cap pulled low, like he just crossed through the yard on his way to the next town over. He's spent years collecting badges and making friends with creatures most people only read about, and he still gets genuinely excited every single time. He asks the birthday child to be his training partner for the day before he's even finished saying hello.
