C.     cousins, often green and striped, or they have plenty of bumps and bruises, although they are

D.     cousins; they are often green and striped, or with plenty of bumps and bruises, although (E)

E.      cousins; they are often green and striped, or have plenty of bumps and bruises, but they are

E. they are .., or (they) have ..., but they are ...
