You just need to present them with three beers.

For the person standing at the bar, you need to bring 5 cups. You can bring a cup, get a coin, and give the coin 5x to do this quickly. After this, you can bring an empty cup for a coin or an empty cup and coin for a beer.

For the girl standing behind him, you need to speak Reuben, then Tij, then her. Speak to her again and she will thank you for talking to her.

Talk to him as an ant.

You must be dressed in a suit and be friends with almost ever other person. I believe I was friends with 124 when I tried.

You will need to return to the bus stop after speaking to Reuben and Aran. Speak to him twice to befriend.

Turn yourself into an ant and talk to the chicken, come back as a human and talk to them again to befriend.

The cones are in Reuben's Room, the sewers, the parking lot, on the stage, and outside the backdoor of the club.

You can get coffee by using an empty cup at the campsite near the beach or in the trailer. It is a larger grey metal machine.

Feed the crow a worm, found in the apple.

Leaves are scattered around the levels, I believe he needed 5. One is well hidden in the bushes by the stage.

Bring a beer to the yellow alien stuck in the ground. He will give you his ticket.

To be his friend, give him beer.

To sneak by him, you need to use the bush disguise given to you by the fairy after you retrieve his wand.

Bring them toilet paper from the party tent.

Either wear the diving suit and enter through the well or any toilet.

The suit is found in the trailer, in the closet behind sandy. You will need to help everyone backstage to get access.

The train pieces are located in the club behind the speakers, in hell to the right, and in the sewers.

To get the treasure you must die with a cup of water. Get the cup and water in any porta potty.
To die, either be eaten by the chicken in ant form or be killed while not camouflaged trying to enter the cave.

Wand is in the sewers. Just give back to the evil fairy near Tom to learn the bush disguise.
