Maybe pictures on Grabbed By the Ghoulies Board represent:
1.Spiral Mountain
2.Door to Banjo House
3.SNS Beach-secret level?

Can you noticed that Rare placed Devil Bottles picture in GBTG in the same place as Bottles picture in B-K: ON FIREPLACE

This is strange that when we start Bottles Puzzle Game in B-K then Bottles said that we will win mystery prize.But after beating all challanges we not win mystery prize but only funny sandcastle codes. I will tested this:
1.collect ice key
2.collect certain eggs
3.play again Bottles Puzzle Game

Another strange is that one of challanges in BPG is places in Blackeye's Bedroom where treasure chest is...and another in captain's'cabin...

Maybe after beating Bottles Puzzle Game with key and correct eggs secret level will activated?
Maybe chest will opened?

Now what eggs we should collect?

My idea:"Complete your homework and finally you will can play Devil Bottles subgame"
