Crouch / Crawl

The player learns how to crouch and crawl through tall grass when they begin the Save Saul quest. This action is the main way to safely explore near enemies that would otherwise see the player.
== Crouching ==
Once the player learns the Crouch / Crawl skill, they will automatically begin a crouch when they enter tall grass (or the aquatic tall grass of Lappy Lake, the shrubs like those in Gongoro Peak, or the Magic Shield) and stop moving. That is, they cannot be walking or using the Whiskers / Sniff Radar. The player only needs to have a small part of their body within the grass to begin a crouch. If they are very precise, they can even crouch very close to grass without quite touching it. 
While the player is crouching, all enemies (and bosses) immediately become unable to see them. Therefore, in most cases, the enemy will immediately start retreating to its default location and restart its default behavior.
If the player is crouching, certain behaviors will cancel the crouch, allowing enemies to see them, and others will not.
Will Cancel:
* Moving out of the range of the tall grass
* Being pushed out of tall grass by an enemy (Especially possible with small grass patches)
* Barking, or charging a bark (Appears inconsistent; further testing needed)
* Throwing a Rock (Further testing needed)
Will Not Cancel:
* Using the Whiskers / Sniff Radar (Note, however, that using the radar and turning can accidentally move the player out of range of the tall grass)
* Digging
* Moving (see Crawl)
Crouching has one major limitation. It hides players from being seen; it does not protect them from attacks. If an enemy is already attacking, and the player tries to hide by crouching, they will still be hit if they're within the normal range of the attack.
== Crawl ==
If the player is already crouching, their movement becomes a crawl instead of a walk or run. Crawling is slower, but it allows the player to stay hidden while moving. Players can crawl between nearby grass patches and stay hidden over long distances, especially where many grass patches clump together, like in the opening stretch of Gongoro Peak. Given the previously discussed generous range of grass patches, players can often crawl between grass patches that aren't touching and stay hidden.
