Apparently the Premium DNA pages list off the accessories:
>The groovy new Premium DNA 1/12 scale Earthworm Jim action figure stands 6" tall. He features 30 points of articulation, and includes his trusty blaster, 3 Snot companions (standard, neutral backpack insert, and action pose backpack insert), 3 sets of hands, and 2 swappable heads.
>The new Premium DNA 1/12 scale Psy-Crow action figure stands 6" tall. He features 32 points of articulation, and includes removable space helmet, grappling hook blaster, swappable space suit and bare feather arms, swappable space suit and bare feather tail feathers, 3 sets of hands, and 3 interchangeable heads (angry, neutral, and disappointed).
>An incredible 2 action figures in one, the new Premium DNA 1/12 scale Professor Monkey For a head action figure stands approximately 11" tall (5.5" of human, 5.5" of monkey). The Professor features 31 points of articulation, and Monkey features 28 points of articulation. Set includes 2 heads (screaming and non-screaming), 3 sets of hands for both Professor and monkey, 3 science test tubes/beakers, and banana powered blaster rifle!
>Standing over 7" tall, the new Premium DNA 1/12 scale #4 action figure features 30 points of articulation, and includes removable armor, 3 sets of hands, special fish bowl gripping hand, and 3 interchangeable heads (vintage toy, neutral expression game, and open mouth game.)
Kind of disappointed Psycrow doesn't come with Major Mucus, even at his canonical size Mucus isn't going to be big enough on his own to be worth $50
