If you don't call it anything, it will be weird saying:

GUY: hey bob where are you?
GUY2: I'm at the risky island thingy on my second round, I risked it
GUY: what is risky island thingy?
GUY2 well it's the risk island event island............
What would happen if it was called goopa island
GUY: he bob where are you?
GUY2: I'm at goopa island
GUY: Kk thanks
