For the Legends of the Hidden Temple costume we bought skate helmets and spray painted them yellow to match with the logos on the shirts (which we did order online). Other accessories we got where padding/ wrist guards, mouth guards and WATER SHOES (what we could find in October, buy them in the summer!).
We wore khaki shorts which they wore in the show, Also we made golden pendants by printed them outline and wore them around our wrists. There six teams so you can have twelve people in this group costume!
It was awesome!
