In the episode of Spongebob where he draws a picture of himself and it comes to life he is using a pencil that was dropped by an artist on a boat on the surface. At one point the pencil is broken in half and he sharpens the half with the eraser (i think im remembering that correctly). Throught the episode the pencil changes length. And even when the artist gets his pencil back its a full sized pencil. Wasnt it broke in half earlier?
