- Creator-Preferred Adaptation: Would you believe Dr. Seuss liked this special more than Chuck Jones' adaptation of How the Grinch Stole Christmas!?
- It appears that the "Max" we see here is a different, albeit similar looking, dog which the Grinch obtained and also named Max after the first one from the Christmas special left him (or, given the fact that the Grinch isn't reformed in this one, this was the first Max to leave him and the Max in the Christmas special was the replacement?). The Grinch seems pretty set in his ways, so why try another breed or go through the trouble of remembering a new name?
- Reversed mostly for the Grinch himself, who looks much closer to his original book design than in How The Grinch Stole Christmas. The Limited Animation however sometimes betrays.
- Trope Namer: For Go to the Euphemism, named after one of Ukariah's lines in the special.
