Why does my house have noodles/pasta/spaghetti on it?

Solution 1:

This means someone teepee'd your house with toilet paper.

If you rest at your housing structure, you will automatically rid your house of toilet paper, and gain 1 Strongness.

However, if you let others continually pelt your housing structure without cleaning up, you end up salvaging some of the toilet paper rolls for use, so you can take revenge on those who dared to tarnish your home.
