Lots of potential
The best part of this was the animation. I felt it was funny how there was such splendid animation regarding the title and the transition effects but the other parts were fairly bland. I suggest you try to throw in some more music and more jokes. It seems like this ended quite quickily and there was not a "To Be Continued" or anything. At least you had some funny jokes like the random "Banana Phone" joke. Geez, how long has it been since I heard that meme referenced?
I also liked the little easter egg with the tiny words. For those of you wondering, it says, "If you can read this, you're too close to the screen". I do not think I am so much close to the screen as I am just a guy who likes at those things. The monser itself had a pretty good design. Try to work a little more on jokes and have more of an ending, but congrats on getting so many voices.
