Chips McGraw's right hand wiener. As loyal as he is moldy, and every bit as strong as he smells. Franko is a mustard-crusted mayhem machine. His onion mace has reduced legions of enemies to tears...literally. Almost forgot, he can belch the score of every 90's action movie perfectly and (strangely) beautifully. 
Grot Dog is a gross hot dog. He has a burnt tip and is encased in a bun that acts like a vest. He wears a pair of fingerless gloves, straps on his ankles, and a single tennis shoe. He is covered in onions and mustard around his face.
