I am really excited for this box. The small glimpse we've been given of the two heroes Rocket and Groot has had me super stoked to see more of how they work. Also, the fact that we know all of Groot's events are various forms of "I am Groot" (and one "We are Groot") is a fun detail and I can't wait to see what all of them do. And Rocket looks like he'll be able to team up with Iron Man due to his being tech heavy.
Can't wait for the live stream tomorrow!
