Doughnuts

Doughnuts are one of the four power-ups in the game, serving as the life system. They are seen scattered around, which, when collected, gives Joe one life per doughnut. To gain access to the treats, much like the rest of the power-ups, they must be purchased from the Coffee Shop once. Upon purchase, they will not only begin to appear in the world, but Joe will also gain an additional starting life. Subsequent doughnuts can be purchased for 250 Cappuccino Coins, and will give Joe more starting lives.

Mentions

Doughnuts are mentioned in the August 2nd edition of The Daily Newsletter, which states that "Francioli is currently hooked up to an oxygen tank and consumes nothing but powdered donuts... 'Its astounding that this man is still alive' says Herald. 'I don't know what his secret is, which is quite embarrassing for me as his personal physician.'", which implies that doughnuts universally have healing properties, which is not known by medical professionals.
