Introduction to the Deep Sea Octopus Monster: Holding the foam skateboard tightly with your hands, the 17-meter-high eight-parallel three-stage slide winds and turns, just like an octopus opening its teeth and dancing claws to invite you to dance. Close your eyes and slide down from the top, feeling the wonderful touch of the octopus. The multi-level sliding fun and speed changes allow you to relax your body and let go of your enthusiasm.
