Crabs Adjust Humidity is a third-party expansion pack for the hugely popular Cards Against Humanity series.
The cards in this deck look exactly the same as the the original game's cards (feel, texture, font, color, etc.) but have all sorts of new jokes and ideas. This way, they can be shuffled seamlessly into the original deck like any other expansion.
Deck is entirely new, unopened
