Sneaking is a feature introduced in Seecret Saturday 1. When you hold the Shift key you'll enter sneaking mode. Sneaking was originally called crouching, however your hitbox doesn't change from the normal standing height.
Sneaking has the following affects:
- You walk slower.
- You make no noise.
- You can't fall off ledges.
- You won't trample crops.
- The camera is lower.
- Mobs still notice you, no matter what.
