Kenny's cave

 is a location in Point Lookout.

It leads to Miner's rest, where Kenny (Point Lookout) resides. You only have access to this shortcut after either completing the speech check, using Child at Heart (Confirmed 360), or retrieving Kenny Bear (his Teddy Bear). Here you can store your things and even become Well Rested when the cot is used.

Appearances
