Transform play time with three great ways to play! The Transformers Build-A-Buddy Optimus Prime is more than meets the eye. This toddler building toy allows kids to put Optimus together with a toy drill that that's great for development of fine motor control. Put together in semi-truck mode, he’s a great push-along truck toy for lots of on-the-floor fun. When it's ready for action, build Optimus Prime up in robot mode, and you can lead the Autobots to victory in an action-ready figure that's almost a foot tall! 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 as much as they want. Each of the chunky robot toy parts are made to be large enough for little hands to assemble. The Optimus Prime drill comes complete with 2 AA batteries pre-installed so that Optimus Prime can join their other Transformer toys right away! The Build-a-Buddy line is fantastic for Transformers fans ages 18 months and up. These kid toys have earned STEAM accreditation from the Toy Association and earned a Good Toy Guide recommendation.
