Mario & Luigi: Dream Team

[Previous]

I... never knew that tbh. I didn't beat the game because I got stuck at one point (I think I was Bunny link at the time? idk) or something.

I... Uh... how do I put this?

I think you're confusing Link's Awakening and A Link to the Past here! You transform into a bunny in A Link to the Past when you enter the golden land without having a certain item yet. In Link's Awakening, Link gets stranded on the shores of an island which is only in the dream of the wind fish.
So in Link's Awakening everything is a dream and Wart appears (I think to the right of the swamp, he's in a cave and throws bombs?).
