Apparently, while in his time off, Lo-Melt donned a snappy serape and headed south of the border. Although this was probably to avoid the authorities, or to cover up some unfortunate "business", Lo-Melt is back now, and back for good.
To celebrate the occasion, Lo-Melt pulled out the old Sombrero from the dress-up box, and did an impromptu Mexican Hat Dance. Witness the glory.
