Back home, the Grinch decides to upgrade the sweeper into a "darkhouse", an anti-lighthouse that spreads beams of darkness.

The Cat becomes livid with the Grinch's hijinks and has a psychiatric session with him in a thought bubble to find out what makes him so mean-spirited.

The Grinch makes it so dark that the Cat can't see where he's going, and he crashes his car when he passes a "Dead End" sign.

There, he leads everyone in a song to remind the Grinch of all of the love he received from his mother and implore him to change his ways and be a better person.

Coincidentally, Marvel's figurehead, Stan Lee, had served in the same division of the United States Army as Dr. Seuss during World War II.

The special was released again on DVD by Warner Home Video on October 18, 2011 as part of the Dr. Seuss's Holidays on the Loose!
