2 questions about Quest for Hyrule 2

[Poppa39]

First question is how you beat the second castle, the floor in the room before the boss injures you when you walk on it.....

Also I am running ZC192B183 and when i look at the map for the second time it will crash on me. Any help would be appreciated

Does anyone know how to get the whistle in this quest? If so where and how?
