Here's why:
* Mii limitations: The Mii creator focuses on creating humanoid characters. You can customize features like hair, eyes, nose, and mouth, but there's no option for animal features like floppy ears, fur, or a tail.
* Content restrictions: The Mii Channel is designed for creating characters that are safe and appropriate for all ages. Creating realistic or cartoonish animals might not be allowed.
Alternatives:
If you want to create dog characters:
* Use other games: Games like "Animal Crossing" or "Nintendogs" allow you to create and care for virtual dogs with more detail.
* Create your own: If you're creative, you can draw or design your own Scooby Doo character on paper, or even using digital drawing programs!
Unfortunately, the Mii Channel is limited to creating human-like characters, so you won't be able to make Scooby Doo or other specific dogs within that platform.
