help! this may be a noob question but i can't figure it out. Ihave 4 dead villagers and can't figure out how to bury them. any help would be appreciated.

That's one of the puzzles and requires a certain level of Village Tech. A good strategy for solving the puzzles is to pay attention to the things that your villagers are curious about and the messages that you see when you take one of your villagers “exploring” around the island. These often provide clues that will help you solve the puzzles. Another good strategy is to drag one of your adult villagers around the island after every tech purchase and look for new things that they can work on.
