Google, per its mission statement, wants to organize the world's information and make it universally accessible. The company also would like you to reinvent yourself by using its numerous products.
For New Year's, Google posted to its official blog, a list of ways to use Google products to eat better, get fiscally fit, travel more, and learn something new. I won't rehash all of that here, but within the post (in the "Eat Better" section), Google included a new video about how to use Google Play to eat better, and took advantage of Sesame Street's Cookie Monster to do so.
This is not the first time Google has turned to Muppets to sell its products. You may recall this commercial featuring the actual Muppets using Google+ Hangouts.
