You chose to move the subordinate conjunction, like this:
Delores makes her infamous rubbery meatballs whenever
David sneaks them off his plate and into the willing mouth of Jellybean,
the family's terrier.
Unfortunately, the sentence makes little sense after this revision. Review the rules for a more appropriate choice.
