When there's a Season 10, It'll be the season when Poof speaks and/or appears in an episode, but I don't want to go too far, let's go back to Season 9.
The only notable episode after School of Crock left is Fairly Odd Fairy Tales, and that episode has Poof in the plot, so we can see and hear Poof talk, but we'll just wait and see on August 1.
Anyway, back to the Season 10 topic, I'm predicting Poof will be speaking and/or appearing in about 10-30 episodes next season.
What do you think about this? Do you want to see more appearances of Poof? How much episodes do you want Poof to speak?
