Lil Gator Game

Once you've collected all the climbing/stamina bracelets from the monkey (named ???), you can find him in the playground town on top of the cathedral-ish building.

Talk to him continuously and he will go through a series of revelations about his true name. After two conversations, this achievement will pop.

But keep talking to him! You can pick up these achievements as well, as the conversation goes on:

After collecting all the bracelets keep talking to the monkey at the town and you'll unlock 5 achievements

All 4 bracelets:

First, find the Monkey and buy the Bracelet from him at each of the 4 locations (this will get you the Infinite Power Achievement)
Location 1: Follow the river on the small island inland and you'll find him standing on the rocks - costs 100 Scrap
Location 2: In the birds nest on top of the Treehouse (Jill's quest area) - costs 500 Scrap
Location 3: On top of the WInd Turbine - go up high and you'll see it in the distance - costs 500 Scrap
Location 4: On a peak in the highest mountain range - costs 500 Scrap

Once you have all 4 bracelets, the Monkey has moved to the play area that you are upgrading and will be sitting up on the roof of the church (Jill is standing beside this building), go interact with him 5 times and you'll get 5 different Achievements including this one.
