Plan
The hat comes to a stop, thinking of a plan. The hat had been pacing around for a while, trying to think of how to get off the head he's resting upon and back into the house where it's nice and cozy, and came to the sudden realization of a plan. This caused the hat to stop.
Imagine a hat walking about on your head, pacing back and forth deep in thought. See the hat stroke its chin in contemplation as it tries to think up a plan to get off your noggin and back inside.

The plan that made this hat stop right in its tracks was very simple. First, obtain the key (き) to the house. Then, use the key to get in the front door. How simple!
Watch as the hat begins to grin. This plan is so simple it’s sure to work. Now watch as the hat obtains the key and enters the locked door. What sort of mischief will the hat get into once inside?
