Gina, it really needs to come out the way it went in, from the top. You don't want something like that to get into the drain line as it will cause blockage. There are two ways to get it out. If you're lucky, you can either reach it with you hand and pull it free or if it's too far in for that perhap you could snag it with a bend wire. Most likely though, you will have to pull the toilet and knock it out from the under side. To do this, turn off the water supply and flush the toilet. Then sponge out the inside of the tank (there's alway some water left). Now disconnect the water supply line. Next dip and sponge the water from the toilet bowl. Any water you don't get out of the tank and/or the bowl will end up on the floor, so try to get it all. You will find a nut on each side of the toilet base, usually under decorative caps. Remove these nuts. Sometimes they are corroded so badly that the bolts will break instead of the nuts unscrewing, but that's not a big problem. With these two nuts removed, you can rock the toilet and break the wax ring seal. Then the toilet can be lifted off of the flange and you will have access to the underside and should be able to knock that roller out. Once you have that done, the toilet has to be reinstalled. Assuming you have a wax ring, this must be cleaned off. Use a putty knife, old kitchen knife, or whatever you can find to scrape it off. Rubber gloves will handy here. When the ring is removed and the horn on the toilet is clean, you can replace the tee bolts and nuts if needed. The tee bolts fit in the flange and will be longer than needed, use the length of the old bolts to determine where to cut the new ones. You have a choice of a new wax ring or the newer waxless ring. If you use a wax ring, put it on the flange and carefully lower the toilet one to it, making certain the horn on the underside fits into the ring and the two flange bolts go through the hole in the base. If you use the waxless ring, disregard the installation instructions and put the ring on the horn first. Now lower the toilet over the flange making sure the snout of the ring fits into the flange and again that the bolts fit into the holes. Rock the toilet and apply downward pressure to seat the ring (either kind) When you seat the toilet on the flange, it should rest firmly on the floor all the way around. Now install the nuts and washers on the flange bolts. These bolts are not used to pull the toilet down into place, just to hold it so they are just snugged down. Reconnect the water supply line, turn it on to fill the tank and you are back in business. Don't try to handle the toilet alone unless you are fairly brawny! They are fairly heavy and awkward to handle. Also lining the ring and flange bolts is really hard to do alone.
