Deponia

-( Story related, cannot be missed )-

To awaken Goal, the bartender gives you a recipe for an espresso. The ingredients are thus:

2 powdered items
- Chili pepper
- Gunpowder
3 liquid items
- Battery acid
- Booze
- Taurine
1 miscellaneous
- Stimulant

Item puzzles within the Emergency Station will reward you with the stimulant, a dentist drill, a scalpel, a syringe, and an asbestos gauntlet. After talking to the Mayor, mess around in the Mayor's room to get booze and a glass. In the bar, collect the cow sign and red curtain. (2/6)

Use the gauntlet to collect the chili pepper from the garden in front of Toni's house. (3/6)
Back at the launch pad where you first launched off, collect the dud firework and open it up for the gunpowder. (4/6)
Collect the sponge from Wenzel's place, soak it in Toni's house, and then clean the car outside the village. With the information you learn about the interior of the car, talk to Hannek and ask for the key. He'll ask for user information related to the former owner of the car (liked pink, into ballet, and the name Sugarpuff) to give you the key. Using the key, pop the hood open, use a drill to dig into the battery, and collect it into the glass. (5/6)
Put the cow sign on the nearby board outside the village to make the bull machine interested. Once he's interested, boil his blood by throwing the red curtain up. Then, use the syringe to extract bull taurine from its pumps. (6/6)

In Toni's Shop, there is a grinder right near the door. Put the chili pepper, gunpowder, and stimulant into the grinder, then operate it to get a powdered mixture. Combine the glass of battery acid with booze, then with the taurine. Take both combined items to the bar in the Alley once more. There's a filter for the powder, as well as a chamber for the liquid. With both of these filled, a small thimble of Espresso will be made and ready for you to collect and use.
