Wham Shell questions about the Krabby Patty

If any of you have no idea what species Wham Shell is or resembles, you probably won't get this joke.

I have watched the Spongebob Movie: Sponge out of Water and I think it was a good film. It got me some laughs, it felt like a pre-movie Spongebob episode and it had some great visuals. Although I have to admit, it wasn't as funny as the first Spongebob Movie and it was a bit predictable.
