Ord's favorite blanket goes down the Lost Forever hole and he has a Big Funky Cloud over him now he is sad, so the friends try to remove the cloud by using methods to make Ord feel better.
Notes and Trivia
After Ord's friends failed to cheer him up again with a parade, Zak says, "Oh, this never ever, ever going to work!" You will hear Ord answer, "Zak's right. I will be sad forever and ever and ever!" but it is different when you use closed captioning. Instead of Ord saying "Zak's right," the text says "That's right."
Ord had a big funky cloud on the top of his head and it follows him where ever he goes, but in "The Forest of Darkness" and many other episodes, Ord turns invisible when he feels sad or scared.
