The Kre-o Transformers Optimus Prime set comes complete with more than 500 pieces, the largest amount featured in any of the 2011 KRE-O sets. Builders can assemble the popular Optimus Prime character in ‘vehicle’ mode as the notable semi-hauler or in ‘robot’ mode to create the leader of the Autobots. When in ‘vehicle’ mode, the truck’s removable cab converts into a mini-command station and the trailer opens to fit the two motorcycles and four unique Kreon mini figures included with the set. The trailer can also be disassembled and built into a command center playset for the Kreonmini figures. When in ‘robot’ mode, builders can blast into action with a projectile launching brick. The Kre-o Transformers Optimus Prime set includes orange traffic cones and cool decorative decals. Launch date: Fall 2011.
