What do ladders and brown goldfish do . Well if you ask me ladders are for people to get up somewhere, slowly, to get something, and brown goldfish are for swimming in brown water (they look like they flew in mud). Ladders are very cool if you think about it. They can be different colors, you can jump off of them, and also climb them. Now obviously jumping off them isn’t safe but what else are you supposed to do. Now with goldfish, how often do you see a brown goldfish, exactly never. How cool would that be there’s no explanation.
