Does any one know a model or set number for my son's broken piece? It's Mega Blocks, a small blue piece Spiderman retractable web where you push a button on the little block and the string recoils back inside the block. All I can get is it's Spiderman retractable web something, but Mega Blocks can't help without a model number or set number.
Without seeing a picture it is difficult to determine exactly what you have, but after a bit of research I think you have MEGA BLOKS set #1916: Spider-Man Super Tech Hero from 2004.
