I log in and grab the fishing daily which is Blood is Thicker. I fly to Amber Ledge in Borean Tundra and hit the lake from there. I like this ledge, btw.
At any rate this quest requires you kill an animal in the Tundra which turns you red,
then you rinse it off in the lake leaving behind a pool of blood in the water, which you then fish in to pull up 5 Bloodtooth Frenzy fish.
Back in Dalaran someone throws me a Happy Fun Rock, which is one of a number of things you can throw to another friendly player and they can catch it. I turn in my fishing quest, get 7 gold, and some useless stuff I vendor and throw the rock to someone else. Then I log out, because it’s wicked late.
