People do pretty amazing things with LEGOs, but not too many people go this far out of the way to build something FOR their LEGOs. YouTuber, BANANENBUURMAN, has done something truly unique by building an underwater tunnel, complete with fish, for his LEGO train. If that sounds excessive, you should watch the video and it will make sense. It seems like he pretty much commandeered the entire back yard of his house to create the perfect environment for his train, it only makes sense that he’d add in some sort of water feature.
