Once i got to Marleybone I started adventuring in Hyde Park, BUT THEN i spotted a silver chest with a BLUE MINIGAME SIGIL! I opened it hoping for something truly rare! Once i did i played this strange game with a little Stormzilla and, well............ WHY IN THE WORLD DID THIS HAPPEN?
Marleybone has more silver chests than wooden chests. These silver chests allow you to play the Shock-A-Lock game which will reward you with more gold and also sometimes treasure card. If you complete the pipes from one lock to the other before the stormzilla hatches then you win the game.
