Here is something rather cool - the Optimus Prime and Bumblebee walkaround costumes made an appearance at the Miami Marlins game with the Tampa Blue Rays recently. The characters walked out on to the field in association with the Give Kids the World Foundation to accompany young Timothy Stahlsmith as he made a ceremonial first pitch. They then stuck around to take photos with fans young and old alike.
