Twitter user Mohikan and his son had lots of fun during the ARMS Global Testpunch which were held in the last 2 weeks.

Mohikan decided to make something for his son to experience the feeling of ARMS battles in real life.

With the help of slinky, cloth, balloon, and some creativity, a simple ARMS contraption was created. The “fists” could even retract after punching the air.

Check out more photos of his son playing with his ARMS below.
