When you first visit the Picnic Table in Grounded 2 and climb to the top, you'll come across a locked briefcase. It's sure to contain some good treasure or Raw Science, if only you can get it open. This is how to open the briefcase in Grounded 2 and collect the rewards inside.
How to Open the Locked Briefcase in Grounded 2
To unlock the briefcase, you need to locate two three digit codes, one for the left lock and one for the right.
Left Side Code

The three digit code for the left side isn't too far from the case itself. Located on the top of the Picnic Table, the number is written on the bottom of the crossword puzzle page. Its near the Cooler, found on the open page of the partially rolled magazine. You'll also notice that the rest of the code has been ripped off. Return to the briefcase and enter 137 by spinning the number wheels. Then use the button to the left of the numbers to disengage the lock.
Right Side Code

The code for the right lock is a a bit farther away from the briefcase than the left was. Head to the lectern, found in Ceremony in the northwest corner of the region. There are Orb Weavers and Northern Scorpion Jrs. to watch out for around its base. You need to make your way to the top of the lectern, climbing up the shelves and side of the lectern. You're looking for the torn piece of paper from the crossword page. Written on it you'll see the code, 514. Return to the Picnic Table and unlock the right side.
Briefcase Contents

Once open, you can climb up the handle to get in or go around the side and jump over to it from the clear cup near the cooler. Inside, you'll find multiple pieces of Spicy Candy, Sour Candy, and Fresh Mints. There's a Milk Molar inside the mint container, one of the best rewards for getting the case open. Under the pamphlet on the left side is an orb of 500 Raw Science, another great reward.
