Puff up

We puffed up the balloons.

Small birds puff up while sleeping to keep warm.

The angry cat hissed and puffed up its fur.

My hand puffed up where the cat had scratched me.

Sore against our will did we of Witchland join with the Demons in that war, foreseeing (as hath been bloodily approved) that the issue must be but the puffing up of the Demons, who desire no other thing than to be lords and tyrants of all the world.
