Alright
I mean, it wasnt bad, you had some funny material and some great potential here. The thing is that the tone of this penguin character does not make any joke funny. Its like this kid i knew in elementary school who would emphasize (overdramaticly) what was supposed to be funny, and where what he thought was funny just made the rest of us kinda annoyed. So yea, try using different tones of voice and see how you or other people respond (if you plan on making another).
Note: dont change the characters voice, just how he presents the humor in the flash
