Easter Eggs & Secret Areas
Warcraft III: Reign of Chaos / Frozen Throne
Hints & Cheats
Most of the hidden easter eggs are scattered throughout the game. Use the "iseedeadpeople" cheat code to find them.
Edgar Allen Poe Poem
Log into Battle.net, enter any chat room, and immediately press Ctrl + Alt + F1 to display a poem by Edgar Allen Poe.
Finish the Night Elf last campaign in Hard mode to see a 20 seconds of Starcraft units in action based on Warcraft 3 engine. (NOTE: This is NOT a scene from Starcraft 2, it is just an example of what Starcraft units would look like on WC3's engine. Nothing more.)
To make one of the various animals in the game explode simply click on them a bunch of times and finally they will blow up in a large explosion. NOTE: The explosion will not hurt anyone else.
After completing the game on hard mode and normal mode, check the credits, you'll see a parade of units while the credits roll, ending in some hydralisks coming out and kill them (not the same as the marine/hydrlisk battle listed elsewhere here).
Most of the units say something humorous if you click them multiple times.
Jimmy the Seal
Somewhere in the middle of the map (Night Elf campaign, Chapter 5) there is some mushrooms with some spiders infront. There is a seal called Jimmy behind them. Click him until he blows and a manual of health will be dropped.
On the human campain where you wait in the city for 30 minutes for Uther, and the Undead are attacking you, there's a small house in the far corner of the city, click the allys mark on your mini map to find it, blow up the house and a crate will appear, blow up the crate and a sheep will appear, kill the sheep and you'll get an item. (thanks:ninjaboy)
Human Campaign: Chapter 6
Look for a fountain to the west. Look at your mini map for a yellow house to find it easier. There should be a few animals labeled as zoo animals next to it. The prison with the owl bears (the big things with wings) there should be rats. Look for the one labeled as Filson the Rat. If you try to kill him you will always miss but if you click on him repeatedly he will eventually blow up and drop the Tailsman of Evasion.
First Mission of the Prologue
Look at the island at the top of the screen to see some pirates guarding "phat lewt".
Undead Campaign: Chapter 1
In the main town area after you get your shade, there are 2 civilians fighting with a large crowd watching. Named: Robert and Tyler (from the movie Fight Club).
Undead Campaign: Chapter 2
After the cut scene in the middle where you find you need the urn, knock down the trees to the west of the green human base. When you bring a unit to the waterfall you see a flash of a baby panda sitting on the shoulders of another panda wearing a sword. It'll have the text written: "SECRET FOUND Panderan Relaxation Area"'
Knockdown the trees in the curve in the path which leads to the Rogue Wizard. A path to the left will lead to a cutscene with the Sasquatch and Elder Sasquatch. The elder Sasquatch leaves behind Claws of Attack 6.
Tichondrius is also on this map and will kill some humans.
If you go all the way south and straight east of Tichondras in the most southern and eastern corner, you will be ambushed (Note: The trees disappear, no need to knock them down) by a Level 9 Golem. He had a pendant that adds 150 to your max mana capacity.
Orc Campaign: Chapter 7
Your tauren units will eventually run into a large salamander named 'Hungry Hungry Lizard,' a play on an old board game "Hungry Hungry Hippos." He'll eat his way through a large patch of mushrooms if you watch him long enough. When he's done eating, he will pop into a splash of green goo, revealing a path that leads to a nifty item, The Lion Horn of Stormwind, which generates a protective aura around your hero.
Night Elf Campaign: Chapter 2
In the area where you get the first set of ballistas. Knock down the trees in a north easterly direction. Near the back, among the trees will be a hydralisk. Bring your hero to it to let it join your party.
Night Elf Campaign: Chapter 5
In the cavern, try and go as far right as possible when you start out. Look for a bunch of mushrooms on the right side with a skull and bone in the ground in front of it. If you hear the priestess comments about the demon bile, you've gone too far. Use force of nature on the mushroom sto clear a path. You will see the path is littered with bones. When you bring units into the path you'll get another cut scene and The Largest Panda Ever (level 10) will come to attack you. It'll leave behind a Necklace of Spell Immunity.
Night Elf Campaign
In the mission where you are about to free Illidun there is a secret area. After passing through the waygate and travelling a bit further, the path goes upwards and there are trees to the right. explore and you will find a path the leads to a teleport that takes you to the shrine of the DopeFish.
