Radica's Cube World interactive stick figure cube toys perform obscene acts on each other when linked together. If 2 cubes are placed together, the stick figure characters will interact. One stick figure will open a "door" and visit the other stick figure in his cube. There are several questionable actions that many parents would be concerned about, but the worst is that one stick figure will go through the motions of what can best be described as manual sexual stimulation or a "hand job" (sorry to be blunt) on the other stick figure.
When I called Radica (who is owned by Mattel) to complain, they said they had no plans to pull this toy from shelves and offered to reimburse me $10 if I sent back the cube toys. I asked to speak with a supervisor, and was basically told I would have to send my cubes in and after their crack team of QA had a look at it, then they'd evaluate. In other words, let's just wait till all the cubes are sold out and sweep it under the rug.
There are numerous complaints on other sites, including Amazon's product reviews, from people who have seen the same thing. For this company to continue to sell these toys to children (recommend age is 8) is completely negligent and disgusting.
