Alright, im not sure if this has been posed before (Looks like it hasnt) But here it is.
YOU WILL NEED:
1) Horde 70 (Prefered) Warrior
2)A buddy or two, perhaps.
Alright, what you need to do is get into the tram as a horde warrior. Get to the aquarium, and look for an NPC named "Deeprun Diver"
Get in range, and use charge. You should now be on the other side.
Keep in mind that only Horde can attack the divers (Or Nessy)...
