This character is Happy Go Lucky. It's a 13 second skit (using anime) and I'll be voicing one other character that this character will be talking to.
The skit is about a product called AYDS, which is a cake supposed to help you lose weight, but the name is pronounced the exact same way as the disease AIDS.
The joke is elevated by the fact that both are smiling happily and being completely carefree, while making a pun, and then continue to be smiling happily as they say their lines.

Because this video is very short, I will be putting the full script on here, and my lines are (like this). If you get chosen, your work is probably done, unless I think you did something wrong.
Remember, she is VERY HAPPY.
