What would I do? Easy. I'd stash a little bit of the money away, so I won't start splurging. My goal is to either snag a cutesy AFK hat, or get my greedy paws on the ninja headband. This isn't enough to get the item itself, but I'd have a better jump start than I do at the moment, Lol.
Another million or so would go towards hooking up my friends. Birthdays are always coming up with my crew, so you can't mess around and show up empty handed. We'll live like kings I tells you! Kiiiings!
