I am actually still slowly working on them. Minnie so far only has a short Incredibles task that collects a little event currency, so she is off collecting Donald hats (12 hours). Randall doesn't have any Incredibles related tasks so he's on the 12 hour Zurg Ears quest.
I'm doing the same. Using Minnie, Randall + Mike/Sully to work on Donald and Zurg still (as well as Pluto and Goofy for overnight). At least for now. I don't want to put everything on hold for the Incredibles event and not all the characters are needed!
I really appreciated how they opened up the land to the right of Screamin' for so cheap, it's so nice to have a bit more land. I was worried about where I could put any Incredibles stuff. Hopefully we'll unlock more of that land too.
I'm on the third bots task and thank goodness for being able to click on the task to find them. The cannon bots are so much smaller and keep hiding behind my buildings!
