Oh dear god no....why did the second Spongebob movie take the Alvin and the Chipmunks route?! I mean the first movie was a classic because the plot was better, the stakes were higher (Plankton taking over the world if Spongebob doesn't stop him), the main and supporting characters were much better written, and because the 2d blending with the real life scenes worked so much better (the 3d just feels really, really awkward).
Besides that they already did the "Becoming Superheroes" route (which was done much better, in my opinion) in one of the Season 2 Mermaidman and Barnacleboy episodes.
