World of Warcraft: What has been hidden

Secret quests:

ZELDA TRIBUTE QUESTS: You can only obtain this quest if you're level 47. You have to go to Un’Goro Crater (to be more detailed it's in the marshland). There you should find a wrecked raft and an old photograph. This find will trigger the quest “It’s a Secret to Everybody”.

Then go to Marshal’s Refuge and find Linken, you help him to find his lost memories. This quest requires to visit multiple places around Azeroth before you will complete 13 tasks chain-quest. Afterwards it will ask you to get back to Un’Goro again and you will get the final part of the quest: “It’s Dangerous to Go Alone”.

Now you will have to find and kill Blazerunner (56 level elite) at Fire Plume Ridge. After you have him killed, take the Golden Flame from the back of the cave and return it to Linken (in Marshal’s Refuge) your effort will be rewarded by Linken’s Sword of Mastery and Linken’s Boomerang.

THE CHICKEN QUEST: You must go to Sal-deans’ Farm in Westfall and find a chicken. To get a secret quest you will have to do the "/chicken" command for the chicken about 100 times. Better set up a macro for that.. Afterwards you should see a message: “Chicken looks at you quizzically. Maybe you should inspect it?” Now take the quest and get the special chicken food from Farmer Saldean. Go back to the chicken and type "/cheer" before you feed him. If you will do this correct the chicken will lay an egg. That way you will get your new rare pet.

Rare pets

Tiny Emerald Whelpling: Go to the southwest of the Swamp of Sorrows and you will find Dreaming Whelps. To get this Tiny Emerald Whelpling you have to farm these Dreaming Whelps until one of them drops it.

Tiny Crimson Whelpling: This pet is farmable in the Eastern Wetlands, there you can find Red, Crimson and Flamesnorting Whelps. They drop this rare pet (1 out of 1000 drop-rate). These pets are worth approximately 40 gold.

Lil' Timmy: Timmy spawns rarely and you may find him in Storwmind streets. He sells only one pet, which is a white kitten (costs 60 silvers, however it can be sold for 5 gold). He can be found between Old Town and the Trade District (in Stormwind). I would recommend you to camp at the bridge between these two districts and level up your fishing skill :)
