Build a monster

Here is the place where you can build your own monster. It is not that much different than what happens with every living thing. Monsters, plants, and even humans have an instruction manual for building and making their bodies work. These instructions use a special code. For living things it is a genetic code.

With Monster Maker you use a unique monster code, called a monster genome, to build your own monster. As you decode the pattern of color dots you will be able to add parts to your monster. When the monster is complete it's time to give it a name and print it out. There are three different ways a monster can be printed - with its genome, by itself, or as coloring page. Happy monster building!
