Dorothy's friends are depressed
Dorothy waits in a corner of CASTLE EXIT: "ID BE OVER THE MOON BUT MY FRIENDS ARE ALL DEPRESSED!!". And how do you even get to her corner?
Nudge 1Where to look
Remember the film. Each of her three friends wants something they think they lack.
Nudge 2A stronger push
The Tin Man wants a heart, the Lion courage, the Scarecrow a brain. None of them have to be the real thing.
Nudge 3Almost there
Her corner is reached from above: from THE CASTLE TOP, drop down between the pillar and the key's platform.
What you needOther problems to solve first
Solve these first (each opens its own page, no answers on the way):
Show the solutionThe whole answer, with a video
Bring three presents: the clockwork heart (FLASH BOREDOM, The machine in Flash Boredom), the war medal for courage (The woman tied up on the roof) and the brain (Reaching the secret lab). Press action at Dorothy once for each ("WHAT A WONDERFUL PRESENT FOR THE TIN MAN!"…). After the third she gives Seymour a bath towel: "ITS VERY USEFUL!". It is, on a space opera set (The machine in Flash Boredom).
Why it works
Dorothy takes one present per press of action, in any order, counting up; at three she places the towel.
