I'll fill you in.
The temptation was a 10 lb pot of candy in the kitchen - hanging on a scale. For every pound of candy they ate, they would get a 1 pound advantage (as a group) at the weigh in. The group had to lose 100 pounds for everyone to be safe.
They played around a bit; took out a pound & put it in a plastic baggie just to see how much a pound of candy looked like. Pulled a prank on Bob; put all the candy - except 1 candy corn in a box & hid it under the cabinet; made him think they had each eaten 1 pound. He was livid - then punished the 3 who he thought was responsible for the prank.

The challenge was a whole group thing too. A Halloween maze with apples everywhere. IF they could collect 150 pounds of apples, they'd get a 5 pound advantage; 200 pounds would get them 10 pounds off their 100. At the end of the time, if anyone was still left in the maze, they would get a 5 pound disadvantage instead. They all made it out; got the 200 pounds, so they only had to lose 90 pounds as a group.

You saw the rest.
