Sly traveled to Venice so that he could grab a gold pen, but a Cane Corso guard caught him trying to steal the loot and is chasing him. Later, Sparky saves Sly Cooper and gives him the gold pen. Note: Sly trying to grab the gold pen is NOT meant to be theft and is NOT meant to break the law, the guard being alerted is NOT meant to be theft and is NOT meant to break the law, and the guard chasing Sly is NOT meant to be theft and is NOT meant to break the law. Note 2: The thing in the Cane Corso's hand is just a flashlight. Note 3: How the Cane Corso red was to show that Sly alerted it. Note 4: The gold thing is just a pen. Note 5: I couldn't find an image of the gold pen in Sly 3 or Sly 2, so I used a similar image found on Bing. Note 6: Why the guard turned red was that he was alerted.
Credit to all.
