Board game - need help

Dear internet,

What is the name of the board game in this picture? (Click for more details)



It's driving me crazy.

I've googled it extensively.

It's not "The Secret Door".
It's not "Trap Door".
It's not "Berk's Trap Door Game".
It's not "Treasures and Trapdoors" or any of the other titles with "door" listed at http://www.boardgamegeek.com/.

The Rainbow Brite bedspread should indicate the vintage.

UPDATE (Jan-3-08): This game is quite possibly "Polka Dot Door". Thanks Aimee!! Anyone with any more info (or a copy of the game) out there should still contact me asap!
