Sleep Ammo

Sleep Ammo is a power-up for Bentley in "Turning Japanese" of Sly Cooper: Thieves in Time. It costs 100 coins and is available after completing the prologue.

Description
Hold to bring up the Gadget Grid and select the Sleep Ammo (second on the left). This ammo allows all of Bentley's darts and bombs to temporarily put guards to sleep on impact. Note that you must switch back to Explosive Ammo (first on the left) in order to use normal bombs before taking out a sleeping guard.
