Baby, It's Cold Outside (2) - S1-E42
Continuity mistake: When King Chalatan freezes Edgar, Edgar's crown falls off onto the floor. After the guard asks "But sire, what of the prince?" the frozen Edgar is shown wearing his crown. But when Megan is singing and goes over to Edgar, Edgar's crown is back on the floor. In a similar mistake, when King Chalatan is crying and his tears fall on Edgar, Edgar is wearing his crown but it is not frozen. In the next shot, Edgar's still wearing his crown, but this time it's frozen.
