Near the door where you enter the cake bed room suite, there is a stand made of mirrors.   There are perfume bottles on the stand.   Reach up and under the stand and tickle what you find. 

Look for a head board to the right of the bed to open. Remove pillows off of it if you have to. 

If it does not, scroll down. 

It is possible that the perfume no longer reacts to tickles.  If that is the case, please move on to the next riddle, which is:

 Investigating deep under the domicile of 

the Happy Royal Pigeon will prove bountiful! 

Scroll Down for more hints, but try to solve this first!

To the left of the bed is a night stand.  Look on the first shelf. 

Investigate under the pigeon. 

Push the button under the pigeon!

Have a great night!
