Stop the Hate Master (1) - S3-E12
Continuity mistake: Bulk has stepped on Skull's hand. We see a close-up of Bulk's foot on Skull's hand. When we cut to a wide shot of Bulk and Skull, Bulk's foot is no longer on Skull's hand, yet Skull is still squirming like his hand is trapped - as evident by Skull pulling his hand to get it free, and holding it when Bulk walks away.
Master Vile and the Metallic Armor (1) - S3-E28
Continuity mistake: When the Rangers are riding horses Billy's shirt changes from a dark blue tank top to a blue striped T-shirt and back.
Master Vile and the Metallic Armor (2) - S3-E29
Continuity mistake: Pink Ranger is suppose to be in Lord Zedd's palace, but after Yellow Ranger says "hope Kat and Tommy are all right" she can be seen in the back.
Answer: Probably to save on costs of filming the same scene. In the reused shots they have always morphed so you can't see the actors. They just have to pay them to do voice-overs rather than the entire scene.
