When the police are watching the boat driving wildly around as a result of Mrs. Puff and Spongebob fighting, they are on a hill watching them from above. In the next scene, the police boat is directly facing a cliff, which Spongebob's boat then drives off of. It would have been impossible to see the boat, the policefish would have been staring at a cliff. Then, in the next scene, the policefish are screaming at the sight of the boat flying at them from midair, as if the boat had driven off a cliff which then completely disappeared. THEN, Spongebob's boat landed ON TOP of them, instead of straight into them as from the policefish's perspective. The animators really need to PLAN AHEAD.
