Continuity: At the end when the sled full of Christmas stuff is on the mountaintop, it starts sliding off the edge. It's going fast enough that it should be long gone by the time the Grinch reaches it, but when he does it's still right near the top of the mountain.

Continuity: When the Grinch has his change of heart, his eyes change from red to blue. However, when he looks up and sees that the sled is about to fall, his eyes are red again.

Revealing: When the Grinch is cutting Max's antler, the cut lines appear on the prongs before he actually starts to cut.

Continuity: When the Grinch puts the antler on Max's head it has five prongs. But when Max tips forward, one of the prongs disappears as it's hidden behind his body. The Grinch only cuts off four prongs, but when Max goes upright again, the fifth prong is still gone.

Other: When the Grinch is cutting Max's antler, the pieces that have fallen on the floor suddenly jump several inches closer to Max.

Continuity: When the Grinch goes into the first house, you can see the Christmas tree in the background and it has a silver star on top. But later when he steals the star, it's gold.
