I just need 11 more carnival dust right now, and then I'll have 200, and I'll donate it. And I'll donate dust whenever I get a bit after that, I just wanted to do the first 200 all at once in one big donation, just to know that I got that part done for sure. But I'll keep doing my best to get enough dust for us to get that star fragment after that. We need that Actually, Nevermind redemption!
Aha! Finally hit 100 =) I'm 8 hours away from my ticket expiring and I have to go to work, so I probably will hold onto this and donate next time I come back into the tent and hit 200. But hopefully I have a better grasp of the dusting cooldown windows next time around!
