Doodedoo

Doodedoo's are interesting little critters.  They are amphibious, and can't see very well, but their superior senses of taste and hearing help them get by.  Their smelling works a little differently from other animals.  Rather than identifying scents through their nostrils, they detect different scents with their tongue, like a snake.  Unlike a snake, however, they register the smell, not as an actual scent, but as a color.  Good smells are brighter and easier to locate, bad smells are darker and mostly left alone.
Apparently they like acorns, too.
