U is for Undwearwater in the Underworld, which is the case for Link in water dungeons, Uncoventionally fighting Unclean things while his Underwear gets soaked!
K is for... Kakariko Village.
And because I don't want anyone to beat me to L, which I have a multistring for:
L is for Lovely Link Lazily Lounging with a Loach on his Line.
