I am not totally sure why I bought Jake other than to compliment Finn. As action figures go, these are pretty awful. Well, their likeliness is good, their function as action figures is the awful part. They barely stand, their articulation is faulty at best, and its a small miracle to get them to stand.
But I had a Finn, and you can't have Finn without Jake.
Jake comes with an extra fist (that is murder to fit on tiny his hand, and that much more difficult to stand). He is a pretty big figure, but like an Easter egg, pretty hollow.
The plus side with the toy is the added BMO figurine.
Adventure Time is now on Netflix so go check it out if you haven't seen it yet, its Mathematical.
