Considering this is your first animation, I guess I shouldn't be too critical.
The idea for the animation was okay and the art and animation was for a first-timer pretty good (more or less fluent animation and well-done art).
However two things were sorely lacking: music and sound.
Now, I barely know anything about animation myself, but I don't think it would be too hard to add sound and music to it and Kirby-soundbits and -music shouldn't be that difficult to come by.
As I said though, I liked the idea and the animation, but it still needs a bit of work.

i like the style, good joke, but it was just a little short.

Hummm...ok.
Let's start.
What did you use to draw? Almost all programme have preset shapes. That will help you to make more beautiful shape for the character.
The time: to short of course. Try to put joke one behind the other.
The good thing is you had song. This is a excellent thing that a lot of people forget.
That all. Keep working. With some time and work you don't know what you can make.

Lol, and that's why you don't do drugs kids! :)

Old joke, but I liked your animation. Not bad for a first try (especially if you watch this portal and view all the other 'first animation' attempts. <_<)
Keep hacking at it, can't wait to see how much the next one improves!
