Hilarous.
The style of the animation compliments the humour of the movie very well. Many of the jokes were hilarous (besides the overused 'toilet humour', only down part) the pace was very fast, but not to the point I couldn't understand what they were saying, or missed out on anything.
Stick with the formula, it works. Everyone thinks the graphics are crap, you should slow it down, ect. But these things actually compliment the film very well, making it a fast pace laugh feast. Only complaint is skip the toilet humour, and stick with the random insanity that you used for the rest of the animation.
