I think something else needed to be added to Dedede's dialogue to better segue into that sick burn, but I can hear the joy in your voice while saying it, and it makes me smile when I repeat it out loud, too. Also, the surprised cloud was a nice touch.
I watched this again on Youtube, and I noticed you had left out the ending with Dedede's lonely shoe. I understand why you did it, but you're subscribe section is only eight seconds long. You could have left it in there for the sake providing that ending.
