The grandiose feast is essentially the same as the Grand Feast puzzle ( Puzzle 11), but with more villagers.

All the villagers should take part of their own accord, although remember that babes-in-arms aren't counted. Another thing is to avoid the temptation of picking up and dropping a slow-moving villager on the pot in hopes of speeding things up. In fact, that will result in resetting the feast: all the other villagers already served will lose their bowls and will start again. There is the danger that the timer will run out and all the food will be gone before they are all fed.

BTW, a crab is definitely not needed.
