Nothing Special
The problem with this movie is that addition of flash created images to the sprites is far too obvious througout - it didn't feel like it was a real 'mario world'.
Plus, your spelling/sentance construction at places could use some work.
Breaking of scenes with sections such as '5 minutes later' can be superb for a laugh - there are certain jokes that work better when imagined rather than seen, but you did this at EVERY scene transition. And the line 'Then something happened' was simply woeful.
I think you had the basis of a good story, it just needs a better presentation, and possibly a firmer ending, something addressing yoshi still being alive in his stomach, will he ever escape? etc.
ABOVE ALL - please dont use library buttons!!!
