Cute and well-done. Some parts felt very cliche - in fact most of it was cliche - but it was drawn and animated very well. I thought it was a bit strange that most of the animation was done with no voice acting, yet midway through the animation there were a few lines of dialogue. Regardless, it kept its simple tone and was consistent and entertaining to the end. I was half-expecting the twist but still found it funny.
The one thing I would ask is that for a four-minute animation, there would be more humor than the one non-sequitur at the end.
