Haha, funny ending.
I felt this sprite movie moved a bit too slow for my tastes, but it was ultimately saved by the funny and unexpected ending. One of two things would've made the flow of the movie better. You could've added some actual voice acting, or replaced the word bubbles with buttons, to allow the viewer to watch the animation at their own pace.
The sprite animations were well done, and the music redeemed the dull sound bites for Mario and Luigi. All in all, I liked it, it was okay. Keep going!
