How to put it together
- 1
Put on the base green or brown jumpsuit or matching sweatsuit.
- 2
Pull the hood over your head, ensuring the padded neck frill stands upright and the three horns point forward.
- 3
Secure the front zipper or hook-and-loop fasteners on the chest.
- 4
Slip on the plush dinosaur claw gloves over your hands.
- 5
Secure the claw shoe covers over your regular sneakers using the elastic bands.
- 6
Adjust the stuffed tail at the back so it hangs freely and swings as you walk.
Makeup & hair
Keep hair tied back flat under the hood. If using an open-face hood, paint three small white horns on the cheeks or nose using non-toxic face paint, or add green scale patterns around the eyes.
