Add the Big Tentacle & Big Slimy Pit to the points of interest tab

In order for new players to learn about the Atrium, they need to kill the Tentapillar.

For example, the note for the Big Slimy Pit says that when you kill it, it leads to another part of the cave map, but there really isn't anything to indicate that one of the sets of Tentapillars in the world will lead to the Atrium. I believe adding it to the key POI would be beneficial for this reason. 

I also suggest that something be done for us older players in regards to finding the correct Tentapillar. Finding the correct Tentapillar for the Atrium is a big guessing game, where the easiest and/or most fun way of finding the Atrium is to either void-walk to the arena or pray that you can telepoof to the Atrium rather than potentially hitting up all the Tentapillars in a world.

Having a way to quickly find the correct Tentapillar would be appreciated.
