Jay - no surprises within the package of Sandman and “Evil Slimer” (He'll always be “Big Green” to me.) What I do like is that they gave Sandman his blow gun in one hand and it looks cool. Because of that, they packed in an extra “regular hand” for him so you can swap them out - but personally, I don't ever see myself doing that. Also, they actually printed the details on the back of “Evil Slimer.” It's sculped smooth, but the printing reminds me of near the end of the episode where we actually see Slimer make the change (with the camera view behind him) and his back just plumps out with all the new ridges and bumps. It was a nice touch. He doesn't have any accessories though.
No real surprises with Louis/Stay Puft either - other than apparently they've decided to change out the Stay Pufts. All the original promo material for this series said that the box set would have angry puft and the TRU sets would have happy puft. Well, angry puft is in the TRU set, so I guess we'll have to wait and see what they pack in the box set. Louis comes with the regular stuff - closed trap on his pack, open trap, and blast stream. (I do really appreciate that with these, they took the time to paint the under-torso of the figures, so you can take off the pack, and they're still in uniform. - They even did this for Louis.)
