As you make your way through the massive-but-short hallway, it leads you into the stalls of Buff's harem. As you recall, Buff is the younger, bolder bull that your grandparents raised.
Son of Charcoal, but he's grown to be at least half a head taller. That's what you think at least, until you notice that his stall at the end of the barn is so large that there's no way it could be meant for just the Buff you remember.
But for that matter, all the other stalls are enormous too, getting larger the closer in proximity they are to Buff's stall.
The milk pails are on the wall, so you grab one and pick a stall to head to.
