Use your fingers to shoo a turkey down the stairs and into a portable carrier. You've been trying to get this turkey into the carrier so you can transport it for like, the past hour. You finally got it done with the help of gravity. And, you know, smacking it a bit in the butt with your fingers.
You needed the turkey to be more portable because you're going to be bringing it to a cake (けい) shop to turn it into a cake. You aren't cooking it! Geez, what's wrong with you? No, you're making a cake OF it, for its birthday. The baker needs to see it for reference.
