It explains that it used to be an attractive hairless cat but had to grow a thick coat when it became too cold. After the five switch off the fan, the animal requests to be completely shaved which they quickly do.

The Pookees show up briefly to pretend to befriend Roodee after he abandons his real friends thinking they don't care about him.

They grow immediately and Father Time tells them that Elephants used to live in these and as soon as he finishes the sentence elephants start rushing up the trees.

The Pookees try to interfere yet again but are thwarted. After restoring Sparkee to his stinky self he promptly knocks all of them unconscious except for Chewoo who doesn't seem to mind the noxious fumes he released. After asking him to teach her how to do that he hooks her up to the "stink milking machine" and she demonstrates her new ability in front of Father Time and the other four. They get sent flying out of the cave from the force and are about to scold Chewoo but pass out from the stench as Chewoo walks out of the cave holding Sparkee's hand, sniffs the air to admire her handiwork and says to him that this is the beginning of a beautiful friendship.
