Thank You for Not Morphing - S1-E3
Visible crew/equipment: In the scene where Prue comes home and finds Andy inside the manor. There is a shot where if you look behind Andy's shoulder you can see half of the body of the director in the background in the observatory room sitting in a director's chair. (00:16:00)
The Mystery of the Frozen Himanuts!! - S4-E30
Continuity mistake: When Sunkern evolves into Sunflora, Ash's bag is on the ground, but in the next shot, it is on him. (00:18:42)
Buttercrush / Fuzzy Logic - S1-E4
Continuity mistake: When Buttercup punches a hole in the wall to see her sisters are being lowered into lava, the hole's initially quite small. In the next shot, the hole is noticeably bigger.
