WOO! This morning good ol' Merlin popped up giving me two quests: Welcome Randall and WELCOME FLYNN. Yay! It's not going to be easy, I've listed their requirements below. For those curios, with Minnie I had two story quests at once for her; one for gardening and one with goofy. Both have longgggg tasks, so yesterday I opted to do the longest of the two which was "Strum a Tune" for 18hrs. That must have put me over the hurdle because when she was finished this morning I got the Flynn & Randall quests. Keep in mind this doesn't mean this quest alone unlocks this, it seems that unlocking more quests to progress has more to do with how many you have completed instead of completing certain ones.
I also got a promo for Maximus! $9.99 for him and 150 gems so I went for it!
