Crafted from tin and 6 inches high by 3.5 inches wide by 7 inches long, this Transformers Optimus & Bumble Bee Domed Lunchbox is the cat's pajamas. I never really understood that phrase, but Optimus Prime and Bumble Bee use it all the time - they are best of friendy friends. They spend a lot of time going 'mudding', which Optimus Prime is absolutely fantastic at but not entirely sure about dear ol Bumble Bee. I mean, his life is already rough enough as is from that dang S-named kid! Bumble Bee would just drive into the mud and stay there because of him. It's okay though, Optimus Prime is great for picking up spirits!
