Super Mario Galaxy Movie Trailer 2 Introduces Yoshi, Birdo, and Baby Mario & Luigi?

Just a couple of minutes ago, Nintendo released their second trailer for the Super Mario Galaxy Movie in a Nintendo Direct, which revealed a lot more than the teaser from a couple of months ago. In it, we see Mario & Luigi finding Yoshi (who was teased at the end of the previous film), as well as less expected characters such as Birdo, Lakitu, and interestingly enough, Baby Mario & Luigi. Unlike the first film, the baby characters don't appear to be in a flashback, so I wonder if they're going to be transformed into babies at some point in the film - I suppose we'll have to wait and see!
