Using the DX Octopus Cube is super easy. First, you can attach it to Zyuoh King to form the wings or propellers and put on the helmet it provides. When you want to have some fun with the tentacles, just move them around freely on the two sides where they can move independently. As for maintenance, keep it in a dry place to avoid any damage. And be gentle when playing with the tentacles to prevent them from breaking. This product is ready to ship with First - Class shipping in the USA, so enjoy your new mecha toy!
