You can get figures from toy shops, poundshops, dolls house suppliers in 1/.12th and 1/24th.
They're not difficult to make a pattern for, especially when they have helmets on and big life jackets. Then find a vac forming company and sweet talk them into moulding them in two halves, glue 'em together after trimming and paint them. Any pose, any size, anywhere...Martini!!
