one thing i found weird is that the episode "Party Pooper Pants" had some markerbob, the song was also markerbob but everything else is normal animation
Yeah, the invitation scene, and underwater sun were markerbob, but the actual episode was normal animation. Same thing happens in Ugh, the actual episode was normal, but the Krusty Krab cutaway was Markerbob. The walk cycles in the Sponge Who Could Fly are also markerbob, but the actual episode is normal animation. I don't know why season 3 specials have the tendency to switch between markerbob and normal animation. You seem to notice a lot of things I notice, great minds think alike.
