I redesigned the hips for a better plug in for the Giant Lego Batman. These hips should plug right in the bottom. I apologize for this being the third update but the other two did not fit right into the lego figurine. This one fits perfectly and tightly into the base of the Giant Lego Batman. My 5 year old was having issues with the hips that were originally supplied. This model is easy for him to take apart and put back together yet tight enough to stay in when being carried around.
