First, you must have activated the ledge that is brought up by the 
correct order of the switches. Also, be sure to have the rose garden 
key. Use a sun card if it is not morning out, then go to the rose garden 
and you should see a red rose in the center area with white roses, press 
the grab button and you will recieve the Thorn key. Take the key to maze 
garden, and go to the locked fence. Open it and get the rose. Once you 
have the rose, be sure to take it the top of the water fountain, and 
place it in there. You will then obtain the half crest A.
