5. Crazy Cow
It was first introduced by General Mills in 1976, and came in chocolate and strawberry. Why were they so special, though? Because they basically covered the kick cereal balls in chocolate and strawberry powder so you could drink this delicious milk afterward.
Like any other cereal brand at the time, they included various enticements to try to make every kid beg their mother for this cereal box. Good marketing strategy! Do you remember the set of Star Wars trading cards that could have been found inside the box as a promotional item? These were extremely valuable because they provided you with cards that were not available in the packs. We were lucky kids!
