Marin Noggenfogger wants you to speak to him again after he creates his elixir.
Now, to mix this powder in with the dew.
Come back and talk to me in a minute... after I have perfected the fabulous Noggenfogger Elixir!
Drink this! It's absolutely wonderful!!!
I knew I had it in me... Oh thanks again, <name> for your help, but please, stand a little to the side, will you? You're blocking my business! I'm going to make millions on the fabulous Noggenfogger Elixir, millions!
What's that? Sprinkle says I owe her a favor? Oh, that Sprinkle, such a kidder!
The entirety of this quest happens at Tanaris
