That’s definitely the biggest one iv seen on all the drain unblocking channels lol.When the one that has been stuck up in you for ages finally releases.I am suprised by the length of it and the strength of him.Nothing like a clogged lateral line to ruin your day!!!Looks like a gutter guard that got pulled in the drain.How could it get so big? I mean the amount of time that had to pass and it didn't just finally stop flowing so I would have to guess that new homeowners are taking care of issues with the property that the previous owners or if it was unoccupied, didn't get taken care of.
