Gotta build higher, gotta build wider. And whoops- oh no- a breach. There's a man down. The moat is flooding, the outer walls have turned to slurry. And a slab breaks away from the central mass everytime a wave slaps at it.
Five minutes- tops- and your work of ages has gone.
One day I'm gonna build a castle sooo tall and soooo fat that the sea is just gonna shrug and go round it.
