The Grinch hatches a scheme to ruin Christmas when the residents of Whoville plan their annual holiday celebration.
Bitter and hateful, the Grinch is irritated at the thought of a nearby village having a happy time celebrating Christmas. Disguised as Santa Claus, with his dog made to look like a reindeer, he decides to raid the village to steal all the Christmas things.
Inside a snowflake exists the magical land of Whoville. In Whoville, live the Whos, an almost mutated sort of Munchkin-like people. All the Whos love Christmas, yet just outside of their beloved Whoville lives the Grinch. The Grinch is a nasty creature that hates Christmas, and plots to steal it away from the Whos, whom he equally abhors. Yet a small child, Cindy Lou Who, decides to try befriending the Grinch.
