Enchanted Tiki Dreams - S7-E23
Continuity mistake: Spongebob goes to set a canvas on the ground. On the spot where he is putting the canvas down, there are three flowers on the ground. In the next shot, after he set the canvas down, the flowers have disappeared.





Answer: I think that this was supposed to be an intended joke. Patrick is too stupid to remember or achieve most things and SpongeBob is able to remember and achieve most things, but the one thing that SpongeBob cannot achieve, is the one thing Patrick can achieve on the first go.
