The Pick Nails are an upgrade available to Rouge the Bat in Sonic Adventure 2. They attach to her boots, allowing her to dig through many different surfaces. Oftentimes she will find item capsules when digging.
- Purpose: Allows Rouge to dig in the ground or on walls.
- Location: Egg Quarters. Go into the Egg Fish Chamber. You will see that there is a room with bars blocking the door way. Use the missile to smash the bars. The Pick Nails are in that room.
- Requirements: None.
- Required For: Completing Egg Quarters. The first time you go through the level in story mode, the game will only allow the final key to appear in locations that require digging, to ensure that you've picked up this item before moving on.
- Equivalent: Knuckles' Shovel Claw.
