BEWARE! Spoilers ahead!
Now that you’ve been warned, just below are a couple of items from Marvel’s Guardians of the Galaxy that appear at the very end of the film, the first is the final scene before the end credits featuring the dancing Baby Groot as he grooves to the Jackson 5‘s “I Want You Back” while Drax (Dave Bautista) cleans his knife blade.
The second is probably considered an even bigger spoiler as an official look at Howard the Duck (who was voiced by Seth Green) from the end credits scene has made its way online. The scene itself can be found online if you search hard enough.
