In the episode where Sandy is hibernating, there are two mistakes: 1: When they Spongebob and Patrick are in Sandy's treehouse, there is no water!!! How could they survive with no water!!! 2: After all the snow had melted (in the same episode) in Sandy's dome, there, again, is no water! They would shrivel up and die!!!
Comment on #1, in the beginning of the sketch, Patrick takes off his water helmet and Spongebob panics saying that they need water, but Patrick replies that since snow IS water, that they can survive. And as for #2, yes your are correct, when spring comes, and Spongebob and Patrick hustle to get out of the dome before Sandy notices them, there is no water or snow, and also afterwards when they are both wrapped around Sandy, this is indeed a Slip-up
Well in the videogame "Spongebob and the revenge of the flying dutchman" Spongebob didn't need water because the ground was wet. Maybe the ground was still wet when the snow melted in this episode.
No.. This is not a Slip up. It's called a CARTOON. The point is that Sandy is going to find out they stole her fur and get very angry at them, not that they have no water. That's like asking, "Why does Sponge Bob have tears when he's under water?" If you don't know that then you shouldn't even be watching this show.
