Walther Splashbone swims with the Shark Club as a German Shepherd who believes the sea is still keeping notes for somebody. Friends learned long ago not to interrupt Walther Splashbone near the drowned subway tunnels, especially with a jar of plastic cards from a flooded mall in hand. Tinkers in the corridor workshops save the trickiest broken pieces for Walther Splashbone to look at. Walther Splashbone once brought a piece of blue tile from beneath the flying den and refuses to say where it came from. Shark Club Member: Shark Club pups are the descendants of rescue divers and deep scouts, the brave water ghosts of the Pixel Pups. The shark hat began long ago as a water training aid for pups bred to enter flooded rescue zones, and the fin still marks the ones willing to enter what others fear. They explore drowned subway tunnels, coastal towers, the lower mall after rain season, and any place the old world left underwater, recovering relics that may explain where Canis Sapien came from and why the sky once burned white. They smell faintly of pond moss, old coins, and victory, paint waves on their dens, wear teeth on their collars, and have each others backs in deep places the way only swimmers can. The Shark Club is one of the two largest sub factions among the Pixel Pups, and Finn is the corgi who first put a paw on the K N L door and made the fin mean something more than a joke.
