Well, here's the thing.
The animation side of it is solid besides getting the lip movement right, but I think what made it not as enjoyable for me personally was the voice acting and writing. It just sounds like either Antfish was trying too hard, or the writing just wasn't enough :-/ I got a few laughs here and there, I just wish mario wasn't temporarily possessed by spongebob squarepants :)
It's not perfect, but it's amusing little short and worth a look.
