Day of The Dead

Got the achievement pretty simple to do, Find Catrina  and /dance with her. Get achievement, coo.

for pet you have to go to the city's grave yard for your race, ie. Draenei go to Exodar, Dwarves go to IF, get cooking recipe from vendor Chapman or find a cook that can make the bread. Buy a marigold or bouquet of them and use it. Find the cheerful spirit, get quest, hand in bread, get pet. Only works during Day of the Dead so only useful for 2 days. And also takes up bag slot, kinda like broom for Hallow's End.
