I call this one The Campfire Song Song
A brief Spongebob art history lesson

In the episode “Artist Unknown,” the figures Spongebob carves out and Squidward accidentally creates are an obvious allusion to Michelangelo’s David.

Michelangelo’s influence is further evident in Squidward’s wise advice: Visualize the sculpture within. The words seem to be an echo of Michelangelo’s self-described process of “liberating the figure imprisoned in the marble.”

Da Vinci’s Vitruvian Man also makes an appearance in the background.
