Kiss 'N Tell - S1-E4
Continuity mistake: After Link frees Zelda from her binds, they stand next to the stalactite and talk. After Link says that kissing him is the only way to cure him of being a frog, and then Spryte says this will be good, Zelda suddenly goes from standing directly on the roots of the stalactite to beside them, and also grows much taller. Link also slides across the floor in a different position. And the color of Zelda's boots changes to an almost reddish brown. (00:12:50)
