Introduction:
This fully 3D Adventure Time game gives you the chance to completely explore the land of Ooo with Finn and Jake. After discovering a ticker-tape machine that prints out mysteries, Finn and Jake go into the investigation business. In a series of connected adventures, they explore iconic AT locations like the Candy Kingdom and Wizard City to solve the mysterious cases. Along the way, they'll interact with all of the best-loved characters from the show. This is the first Adventure Time game that features the entire voice case from the cartoon. The focus is on exploration and puzzle-solving, but there are plenty of chances for Finn to bust out his sword and go nuts too. Between cases, you can even kick back in the treehouse, hang out with BMO, and pile up tons of treasure.

Abbreviated Walkthrough:
Adventure Time: Finn and Jake Investigations has an autosave feature. Meaning there is not chapter select or any save slots. So if any collectables are missed or forget to complete something. You will be forced to start a new game.

Now the main focus here is to complete all 5 cases, Sweet Sweet Magic, Lumpy Ice Princess, Sour Notes, Everything Must Go, and Album (Re)cover. As you complete these cases you will unlock majority of the achievements as they are story related. Also advise to listen to The Grayable's tutorial as he will teach you how to interact with certain objects and how to combine objects with one another. It's recommended to follow the step by step walkthrough above to help you solve these cases, find collectibles and help complete the game without missing any achievements.

There are also a total of 8 missable achievements, "I See You", "Snail's Pace", "Wrong Number", "Radio Starchie", "Stretch Goals", "Combo Time", "New to Ooo", "Flimpin' The Diode", so following a walkthrough will definitely help you not miss any of these and avoiding a second playthrough.

A complete step by step walkthrough can be found HERE by PT user themindisacity.

Conclusion:
Adventure Time: Finn and Jake Investigation is a very easy 1000 that can be completed in an afternoon following a step by step walkthrough. If you are a fan of the Adventure Time show then this is must play for you.

You can also follow the step by step walkthough found HERE.

First investigation:

- Snail 2: When you first gain entry to Ron James' Shop, it will be to your right near the fireplace.
- Snail 3: When you get to the lowest level of Ron James' basement (when you go through the manhole), it will be sitting on a pipe near the far right of the area.

- Snail 6: Near the very end of this investigation the Snail will be sitting at the bottom of the stairs in the Fiona and Cake archives. DO NOT click on the Lumpy Space Princess before you try and click the snail as this will end the investigation.
Third investigation:
- Snail 7: When you reach Magic Mans house derelict house, this snail is by the front tire of the green car.
- Snail 8: Before you fight the third boss you will be helping the Lumpy Space Princess by turning a giant speaker. The snail will be sitting in plain sight near the bottom of the screen.
- Snail 9: As soon as you break out of Lemongrabs Cell, he will be sitting on the top of a barrel nearby at the northern end of the room.
Fourth investigation:
- Snail 10: This snail is in the Fire Kingdom core. After you raise the second bridge you will see him sitting on the wall below the scaffolding. When you approach it, you'll trigger a combat sequence. After you complete the combat you can interact with it.
- Snail 11: This one is a bit harder to find. When you are in the cave, to get a quest item, you will have to use Jake to be lifted up to two platforms in one section. On the top section you will interact with a blue crystal to get a quest item. The snail is next to this blue crystal. It is in the section where you have to get a wand from a golden dragon's mouth.
- Snail 12: At the very end of this investigation you will burn a bill of sale. BEFORE YOU DO THIS, go to the yard sale table farthest from Marceline. The snail will be sitting on top of the table.
Fifth investigation:
- Snail 13: When you go back to the Wizard City, the Snail will be sitting on the stairs of the shop between Ron James' shop and the vending machine.
- Snail 14: This snail is in the Palace of the Ice King. The snail is located in the bottom of the Ninja Armory Room, the same location where you used underwear to fire old pizza at the rebelling penguin.
- Snail 15: This snail is sitting in plain sight immediately to the left of the Flame Princess when you first go to recruit her into your band.
