How to put it together
- 1
Put on the green jumpsuit or your matching green shirt and pants.
- 2
Tie the royal blue eye mask around your head, lining up the eyeholes so you can see clearly.
- 3
Slide the blue elbow pads up to your elbows and the knee pads up to your knees.
- 4
Fasten the brown belt around your waist, positioning the 'L' buckle directly in the center.
- 5
Slip your arms through the straps of the turtle shell backpack so it sits securely on your back.
- 6
Tuck your dual toy katanas into the straps on the back of your shell or slide them into your belt.
Makeup & hair
Since the blue mask covers your eyes and your head is bare, no complex makeup is needed. If you have long hair, tie it back tightly so it fits comfortably under the mask or a green swim cap.
