"MadBalls" is a brand of toy that comes back every ten years or so. When I was a kid in the 80's, you could bounce them and throw them like actual balls, but since 2007 they're more like squishy stress-grip toys. Thankfully they've retained their disgusting and repulsive designs, but with a toonier look. This new blind back features really tiny versions of the "MadBalls" gang, so it's basically like a fidget toy. I ended up getting one of my favorites, Slobulus, and this new design gives him some slick hair like a greaser or something. It's almost a pompadour.
I'm not sure if I'll get another one of these, but I hope they gain popularity. I wouldn't mind a re-release of those "MadBall" action figures. Those can get pricey on eBay.
