Although originally aired before "Out of Odor," this episode does take place afterwards. After reading the whole review on both episodes, I really felt sorry for poor Fifi! But this episode shows how she does indeed escape Elmyra! It sorta doesn't make sense why this episode should air before "Out of Odor" when this episode actually takes place afterwards. But my guess is that the writers just wanted to show us the events that happen after the toons (including Fifi!) get caught by Elmyra. But other than that, this could be a perfect place to end the series! Elmyra, after all, has learned a lesson here! As the toons would say, "So long, Elmyra!!"
P.S. Whoever scored this episode as mediocre is an idiot!
