Scrapers and Scoopers - cooperative not competitive!
I can only assume players don't know this: You can scoop and scrape with two people at once, so instead of racing to get there first, wait a sec and let the 2nd person catch up.
Yes, thank you! So many times I've been scraping and had people rush by me to get the last barnacle, to my annoyance. Sometimes I try to tell them that two people can scrape, but I actually had one Glitch tell me, "No you can't!" :O
