In the episode "Prisoner's Of Love" the scene where Sam and Tucker go into the Ghost Zone in the Specter Speeder to look for Danny, they spot Dora (dragon ghost from "Parental Bonding" and "Beauty Marked") and stop to ask for directions. Notice that Dora is holding the amulet that allows her to change into dragon form. When Sam calls out to her, she transforms-only the alumet is on her neck! How is that possible when she was clearly holding it in her hands and had no time to put it on her neck while transforming???
