Story behind this drawing:

Gruffy and Lucky are trying to get to the donut shop all the way across town, since it is the only day of the year that they will be giving out 5 free donuts to everyone who buys a small coffee.

The two both run into a huge traffic jam, and without much time or options, Lucky gets an idea. He stuffs a hose into his dog pal's mouth and starts blowing him up big enough so the two can float over all the traffic, and make it to the donut shop on time.

Only one problem remains, how is Gruffy gonna deflate when they get there?
