Mesh error when viewing/exporting

[bingusgaming490]

I went to export a model and it ends up looking like this
I even went to use the -view function and it still looks like that.

I exported this model with MKDS Course Modifier and it doesn't do this so what's happening here?

Here's some of the files that don't work well, it's from the Monsters vs. Aliens game btw
