In Frankendoodle, at the end of the episode when Spongebob gives the pencil back, you can see that the two pieces (the original point, and the part with the eraser) are taped together. But when SpongeDoodle had the eraser end (when they were fighting), he sharpened it. So how could he have taped it together if it has a point? And it's still the same size as it was in the beginning, but it was sharpened so it should be smaller. Also, about the taping thing, if Spongebob had cut off the top (to make it easy to glue) it would be shorter as well.
