Whoa, this should be in another forum. Anyway, you're gonna have to play with the "manual mood override" light and the scene change...thing. (It looks like sparklies)
Well, I got walkthrough help on IGN. Barry Scott Will has an excellent one. Anyway, this is his advice:
You begin on the land/happy scene, without figments. Each of the six scenes
has its own set of figments. You'll get the figments from the land/happy
scene later. For now, explore land/sad, water/happy and water/sad.
With the scene set to water/sad, use the megaphone Becky gave you to run
Knight of Joy. The Knight comes out and kills the dragon, allowing you to
get to the higher level of the set and pick up another script: "The Day the
Mail Boat Finally Came".
Give the new script to Becky and run it. Jump on the mail boat to be taken
to the mail/sad scene. Collect the figments and the script, "Goodbye
Hagatha Home". Change the mood to happy and collect the figments from the
mail/happy scene, then use the sparkling portal to change the set. This
switches to the water/happy scene and you can get the figment from the
Use either portal in the water/happy scene to change to land/happy and
collect your figments. Then change the mood to sad and run the "Goodbye
Hagatha Home" script. The balloon will come down. Use the poles on Hagatha
Home to swing up to the balloon and be carried up to the catwalks.
