We´re starting the event in the Prehistoric Jungle, where we want to find a cavewoman for our caveman.
For starters, let´s follow the caveman and see where he takes us. Shortly, you´ll see he really love rocks 😀
In the very first puzzle you encounter, it´s necessary to place the shaped rock to its place. Spoiler alert! You´ll encounter more similar puzzles in this location 😅

Second puzzle, more shaped rocks. Our caveman just loves them all! You should be able to figure this one rather quickly.

As you proceed in the location, you´ll come across another puzzle with shaped rocks. No big obstructions, just put them to their spots as shown below. To continue completing the quest, please use the exit on the right side, to collect the treasure piece, explore the cave with the treasure hint table.

In the next part of the location, our caveman meets the love of his life but to realize that, you have to put a stone in front of her so she can hunt the mammoths.

Also, when you´re done with the quest here, you can light up the fire and help another fellow caveman.
You can also check the hint table, it might get handy for some other location in this event.
Last but not least, the three stones look suspicious, what happens if you place them, let´s say, on the bones?

Well, there´s only one way to find out 🙂 Good luck!
