The one-person woolly mammoth costume. In making animal costumes, we use many materials to improve the comfort of the performers. We try to reduce the steel structure of the interior space and use more rigid materials to support the outline. We solved the ability to open and close the mouth to make sounds and wink while walking on all fours. A positive magnet is installed at the tip of the nose so that the bottle or stick prop equipped with the negative magnet can be well attached to the nose. All of the above designs are wonderful to enrich the stage representation of the mammoth costume.
