In " The Mountain", Jake says he is making hot cocoa, but again, the beverage isn't actually seen, but it is most likely just the camera angle. There has only been a liquid seen in the cup once, and this was in " Abstract". A brown liquid was seen in it, but is unknown what it is specifically. In " King's Ransom, there is steam coming out of the cup, but nothing is seen in the cup, most likely because of the camera angle.

It is a white cup with a flower made of thin lines. The top is smooth, the bottom is bumpy, and there is a handle on the side. Jake says "See this cup? This is literally my favorite cup" and then throws his cup out the window during a Knife Storm to teach Finn a lesson in the episode " Puhoy". In " The Jiggler", jake dips a tea bag in the cup for a moment, but the tea isn't actually seen. However, it is most likely just the camera angle.
