In the title card, Cosmo writes from Da Rules into "Cosmo Rules" with a crayon.
This episode reveals that rule free wishes are controlled by Da Rules which means that rule free wishes cannot be done unless Da Rules allow them to be done under certain circumstances. If Da Rules is not able to control the said wishes due to no rules in the book, it will start to destabilize and if it gets destroyed by the rule free wishes then the universe is destroyed too. Da Rules may also have control over the rule free muffins since whenever someone uses it to make a wish, nothing bad happens.

When Jorgen says "And here is the really back part; if the book explodes, so the universe!" Timmy' eyebrows are colored the same brown' scheme as his hair.
