Transform play time with three great ways to play! The Transformers Build-A-Buddy Optimus Prime is more than meets the eye. Put together in semi-truck mode, he's a great push along toy for lots of on-the-floor fun. But build him up in robot mode and you have Transformer who's almost a foot tall and ready to lead the Autobots to victory! The fun doesn't stop there. This 20-piece construction toy comes with a drill and one bit that lets kids take it apart and put it back together again. Made of chunky parts, it's easy for little hands to assemble. The Optimus Prime drill comes complete with two AA batteries pre-installed so that the fun can start right away.
