Mario in Hyrule Castle?
Can only do before you get the Zora's shapphire!
First go to Hyrule castle and sneak past th guards. Then sneak past the guards in side the grounds until you get to a place called the courtyard. The courtyard will have a young princess Zelda and 3 windows, Zelda will be standing at the forward window so go right and look through the window...
You might have to move your self and press up on the C button to see better.
The Paintings are set out like this:
[Yoshi] [Peach] [Mario] [Bowser] [Luigi]
