Rudolph the Red-Nosed Reindeer & the Island of Misfit Toys (2001)

Continuity mistake: In the shot of everyone chanting, "disco ball!" Hermey is seen in the background, but two shots later, Hermey has disappeared. (00:19:00)

Hermiee: Looks like rough weather ahead. We'd better go back.
Rudolph: I kinda hate to miss my date with Clarice.
Hermie: That doe certainly has you head over hooves. Doesn't she?
Rudolph: Who told you?
Hermie: Everyone in Christmas town knows.
Rudolph: They do?
