I do understand about Classics Hiss having less snakes than the original, and I get that you're not trying to be mean, and IN THEORY I think all Classics stuff should be better updates of vintage stuff, but I think this was one time when they went against the vintage design for a better result (like they should have done with Clawful and Snout Spout) because I think that teeny-tiny 6th snake just looks freaking silly, and makes Hiss as a whole come across as way less intimidating. It's like "Oh no, look at all those big and threatening snakes! I should run buuuuuut look at that little baby snakie! He's so cute and wittle and adowable I don't feel threatened by anything having to do with that little guy!"
And yeah the arms are skinny, but if they made them much thicker I don't know if he'd be able to stand. Maybe he could still stand if they made them thicker and shorter, but then they'd be closer to the first two awful Hiss toys; everyone, including myself and Eric Treadway, understands that the concept behind him is a rolling mass of powerful snakes, but the thing is that in toy form it's never been anything more than a concept; NONE of his figures have ever had a rolling mass of powerful snakes--not even close! The first two toy versions were just silly and not AT ALL threatening, due to the restrictions of the disguise. The first two figures were like "Ok, I'm gonna snake bite you, but first we gotta get close enough to hug!" The Classics version looks like he's gonna come out and get you, no matter how far you try to run.
