‘Child’ is the first of the five worlds in the Game Boy Advance adaptation of Rayman Raving Rabbids. It is an amalgamation of two worlds originally intended for inclusion in Rayman 4: Picture City, and the World of Toys. Picture City was also one of the six worlds found in the original Rayman game.
At first glance, the Child world appears to be simply a return to Picture City, in that it shares many of Picture City's typical characteristics: the environments are cluttered with giant pencils, erasers, pencil-sharpeners and pins. However, a strong influence from the World of Toys can also be found: the Child world is littered with bouncy balls, jigsaw pieces, building blocks, toy robots, train tracks, and many other childish distractions. It is unknown why the developers chose to merge these two initially-separate worlds, but limited time and money are likely explanations.
