Rubick's Cube takes on a dark twist with the Brain Cube. It's just like Rubick's puzzle, but instead of matching colors, you match the folds of the brain. It's pretty cool if you like brainteasers, but let's be honest: this toy needs a hearty splash of blood. Maybe a bite mark. You know, zombie it up (and disguise the fact that this is kinda-sorta an educational toy.)
