Character description from package back: 
Bumblebee and Sam were best friends almost from the moment they first met face to face.  as they learned more about one another, that connection grew deeper and deeper.  Now, whether Sam is behind the wheel or standing side by side with his friend, they work together as a team.  Against Bumblebee and his human friend, no Decepticon stands a chance.
