It is actually a Rubies adult helmet! The shoes are just little (sorry, not sure what you might call them) 'plimsoles', or school gym type shoes with elastic at the side, painted. The moulded chaps on the battle buddy had to be removed as it was constricting the ankle, so her mum made her little craft foam replacements.
So you get the rubies adult helmet.ok I was thinking it would be too big and look off.
