Barrels are objects that first appears in Sly Cooper and the Thievius Raccoonus. Sly and Bentley (in Sly 2: Band of Thieves) are able to jump in them and walk around, and as long as they aren't moving when they are in a spotlight or flashlight guard's light, they can't be seen.
First introduced in Sly 2, TNT barrels act in the same way as other barrels, but they detonate a few seconds after jumping out.
Cherry Bomb 500
The Cherry Bomb 500 was a very powerful type of TNT barrel that looked identical to a generic one. At Rajan's spice temple, the Cooper gang stole a large ruby and traded it to a local crime ring, in exchange for a Cherry Bomb 500. It was later used to blow up the temple's elephant mouth to flood it and draw Rajan out of hiding.
- In PlayStation All-Stars Battle Royale, one of Sly's attacks is the TNT barrel, called "Explosive Barrel" in the game.
