Is there a way to make Item Cards respawn? (3DS) I'm stuck in a loop on the WW map, where I need a boomerang to defeat a Big Octo, but it's locked behind a Stone Head, which needs Power Bracelets, which are locked behind a switch, which needs the Hammer, which is only dropped on the square with the Big Octo. 

I obviously wasted an item on a non-essential progress square along the way.

Is there any way to encourage the item cards to refresh?
