Continuity mistake: In the wide shot of the town square after the mayor says there "is no Grinch problem here!", the yellow car that had a full cab that the red car hit is missing, and the red car's right headlight that was knocked out in the crash with the yellow car is back in place.
Continuity mistake: After Cindy thanks the Grinch for saving her, he stops at the door. He slides his hand down the glass, and it comes off the glass well below his chin level. When he turns around, it's just at his chin height.
Continuity mistake: When Lou enters the classroom, the teacher's yardstick switches position from straight up and down to flat as the shot perspectives change.
Answer: Then why does it appear as a tiny speck in Horton Hears A Who?
In "Horton Hears a Who", both the book and the animated film, the speck of dust lands on a clover. In the 2000 Grinch film, the speck of dust has now landed on a snowflake because it's winter time. It should be noted that it's only the 2000 Grinch film that has Whoville as a speck similar to Whoville in "Horton Hears a Who." In the book and other adaptations, Whoville and the Whos are normal sized and probably located somewhere in Massachusetts.

Dr. Suess was born in Springfield, MA and there are some that claim the drawings in the book are similar to Easthampton, MA and Mt. Tom (although others say it's La Jolla and Mt. Soledad in California). Residence of Easthampton put on an annual "Whobalation" to celebrate the legend Whoville is based on them.
