- Rowdy Roosters: These birds are completely mechanical, they have grayish-orange heads with black undersides, a reddish-gray crest and a greenish-gray tail and black beaks. They can attack with their razor sharp tail feathers.
- Maniacal Marmots: These small mammals are completely mechanical. They are slightly rotund and are light brownish-gray in color with red eyes. They can attack you with their large iron-clad tails.
