Nearly perfect.
Everytime you animate I always expect pure gold, and this was nothing short of awesome. It's pretty funny, I only took basic Spanish, yet I realized how flawed your speaking abilities were, haha. Don't worry, I didn't count off for that, if anything it added to the humor. It reminded me of Dora the Explorer, only reversed, or a childrens show that is based on the same prospectus.
The ending was very clever, I liked how the children in the background were laughing at the dog. The only thing I took off for was the dog doing trial and error with the pants became pretty redundant after a while. Besides that, the animation, storyline, and voice acting were all highly entertaining. Always a pleasure, Boogley. Keep up the great work!
