Hand 4 of them to Maixx Yzi (an iksar) on one of the piers. You get some experience and coin.
Hail Maixx Yzi
Maixx Yzi says, Well, hello there (yourname here). I've been piecing this dock together for the last several days. It was somewhat of a simple task. I'm pretty good with work underwater. I can find I can easily hold posts in place with my tail while I work with my hands and feet. An advantage I suppose. I would guess that's why I was asked to help Morden. Now, I'm working on creating some very strong glue we will use to seal parts of the hull of the ship we're building. Thing is, I need a lot of cove frog eyes for this job. If you want to [aid] me, I could reward you and give you some information.
You say, I will aid you
Maixx Yzi says, Wonderful! If you could bring me four cove frog eyes, it would be a big help.
Hand the guy 4 cove frog eyes.
Maixx Yzi says, Great, I'm working my way through a batch of glue. I keep it hidden so no one is tempted to steal it or play a practical joke on our friends. Here is your reward. I'll also tell you that I used to be a common thief, but not in the way you think. I had to steal a few supplies now and then when I lived on the lands as an exile. But then Morden Rasp found me and I haven't stolen a thing since!
