HELP! my son just dropped my daughter's poly resin(?) frog and it broke. I can't buy another one as they no longer make them and although it only cost a couple of pounds it has ENORMOUS sentimental value. There are a couple of bits missing so i can't just glue it together. Is it possible to patch it up and repair it some how? It doesn't have a smoth surface so lumps and bumps wouldn't really matter.Thanks
