You need kulen.
How can you have any pudding?
the rulebook mention 24, and that number is on every page and i have 18 of them instead.
Rainer addressed this on kickstarter:
This is an example of where you can look at something a hundred times, and still get it wrong. There are six large punch boards with 3 debris tokens on each. Obviously 3×6 = 18 ... but at one point, that was mistakenly calculated to be 24.
So you should have 18, and the rulebook has an error.
