Halloween is Grinch Night

In Whoville, on a night known as "Grinch Night", which commences when a "Sour-Sweet Wind" blows and a chain of events causes the Gree-Grumps and Hakken-Krakks to prompt Grinch into terrorizing the Whos, as he believes such nights are the perfect nights for a Grinch Night. Later, Euchariah, a polite little Who with a slight astigmatism, goes to use the outhouse (referred to as "the euphemism" in the story), but is swept away to Mt. Crumpit by the wind.
