Not to be confused with the Ice Costume.The Glass Costume is a costume obtainable through completing level 24 of the Rubbish Dump Mission. You can view the pets that can wear this costume here. This is like the Glass Paintbrush on Neopets, in which it was retired so people can't use it anymore, but unlike Neopets, you can still use retired costumes on your pets. Glass pets are clear and a lighter blue than Ice pets. The costume is a medium-sized piece of broken glass.
