I was playing
Ocarina of Time 3D
and caught a Poe in a bottle at Kakariko Graveyard. I was going to put the bottle away, but instead of tapping "item" I tapped on the bottle itself. It was too late to stop him; I could only watch in horror as Link raised up the bottle and drank the ghost in a single gulp.
I'm assuming he'll have an extremely awkward trip to the bathroom later on, but I've never heard of any first-hand accounts and I myself have never shat out a ghost, so I have no idea what he's in for. Any advice?
