The silver bloon is a metal bloon that has 25 hp and holds 2 copper bloons. There would be a page for copper bloon, but there is already a page that is in the way named copper bloon. when this is removed i can make the page, but until then i can't, so you'll have to go to its grandchild, the Plastic Bloon. It has the same charachteristics as a lead bloon, except it's stronger and is ALSO immune to PLASMA. you need sungod to do any damage to, and still then it takes about 5 sec. to pop. it is only popped by glue if it is upgraded to bloon dissolver. It is held by a Gold Bloon.
