Nothing says "Rocking" good time like a bunch of colored rocks. And nothing says kicking good time like magnets. Combine the two and you get:
What the heck? You mean that all this toy does is stick in colorful rocky clumps? Perchance we should next begin marketing the Big 'ol Bucket of Mud playset.
