If you need help, read this topic.
When you enter the room, free the villagers, using the keyholes.
To use the Rainbow Key, simply cut the rope.
There are some secrets. Try breaking the pillars.
To unlock the scientist, open up the secret room. You will find a keyhole. Open it.
Evil Kazooie (or friend whatever) will summon evil dragons to attack you. Defeat the dragons.
Then, the evil ink will escape Kazooie. Then it will go on you. I wonder what happens if your health reaches max. Will you get possessed? Try it!
Walk up to the villagers. They will plant a giant tree (you know the weakness of evil ink, right...?)
Also, if you don't collect all the jiggies, Kazooie will die (cause she fell in the pit) Luckily, I thought you need all the jiggies to complete the game. (Stupid me).
Then the credits will play. Do NOT press the start button that has a birds eye view picture of the village. I repeat, Do NOT press the start button that has a birds eye view picture of the village.
Am I a bird?
Yes Kazooie you are.
THEN PRESS THAT BUTTON!
