who are those rats?

• the rat in the orange t-shirt is the main guitarist. he seems to be the oldest but no one knows for sure.
• the rat in the leather jacket sings lead and plays the bass. he also writes most of the songs with the rat in the orange t-shirt.
• the rat in the cap wandered in one day and wouldn't leave (possibly because he was wanted for questioning). he occasionally plays a solo and cooks quite well.
  
• the rat in the red jacket is the drummer. just the drummer.
