From little tikes, it's Kingdom Builders!  Build, Bash, and Remodel!  

Here's Sir Hammer of Head, the warrior that turns into a hammer! 

"Nailed it!"

Kingdom Builders takes place in the magical Land of Buildera, where you can build anything you want! The creative, Armor-clad Builders must defend Hex Castle against the mischievous Bashers and their Wreckin' Roller. Only you have the power to decide who is a winner and who is a tool!

Please note - the plastic packaging has a split and the cardboard has a dent in one of the corners (see pics).
