When Orko first picks up Spydra's wand and uses it on magic beans, it has talon like fingers sculpted around the crystal orb. The next time we see him, as he is stuck in the beanstalk, the design of the wand has been altered, the talons are now much simpler triangular shapes. This is especially noticeable during the moral segment, where both scenes are shown in order as part of a recap.
When Cringer runs out of the dining room after being frightened by thunder, the door is much too small in relation to his body.
Teela grabs Spydra's wand and snaps it's hilt in two. But later Orko somehow produces the intact wand from his sleeve.
When Montork says "It worked, didn't it" to Teela, he turns his head but his beard remains in the same place.
