A very simple addon with a command that you can put in a macro or just type to your hearts content. It lists Pepe toys and other pepe items. Things like Viking Pepe are considered quests so if you would like your pepe whistle to show the viking pepe on all your characters you have to have completed the "quest" for viking pepe on all those characters.
Since I'm an altoholic it started to get rather hard remembering what all my characters had done and doing it by macro started to get too complicated, I made this addon to help me.
The basic addon is just the "/pepe" command.
If you have TomTom installed it will provide with clickable links to add destinations to Pepe's all over Azeroth.
