Is it a bit weird to see kids slice open the body of an alien and then remove slime and organs from its carcass? Sure. But damn does this toy, which is part slime-toy, part science toy, make the process fun. Kids cut the carcass with a knife (don’t worry, it’s not sharp) and pull out the contents — which include a collectible alien action figure, body parts and, of course, ooze. And it can all be played with again and again.
