Just the carrot, and a tin cup i found in the carriage. I'm at the beginning of the game and clicked on everything interactable. How do I find this metal pipe?
keep in mind that if you're stuck, chances are you haven't actually found everything interactable. have you checked the windows? both? what about the rest of the carriage?
I did talk to the carriage driver and he says the same thing, "i'm still waiting for my pay." And yes, i do have that tincup, i see that there are other tincups as well.
try completing the set of cups? maybe it belongs with the others. to 'use' an object you gotta click on it and then click on where you want to apply it
