It's the mating season for dreary scuttlers and Scuttles sends you to find a mate for him!
Grab some rocks (black sparkles again) on the beach ( 6, -4, 557 ) .
Approach any scuttler and bring it back to Scuttles... To his dismay, it's another male!
Grab some more rock.
Approach another scuttler, hoping it's a female and bring it back to Scuttles. Lucky you, that one was a female and they're basking each other in worship.
If you return to the beach after 30 minutes, the two loving scuttlers will have had a whole bunch of hoorific and terrific baby scuttlers. If you speak to Jenni, she'll let you get one to... er... decorate? your house!
