First image shows Peter Pan needs to be a 5 to collect for Timothy with John Darling. The 2nd image shows that Mulan can do Fan Flight at a level 1 but the wiki still says she needs to be a level 2 for it. Finally in regards to some of the taks Mickey can do in his costumes. It isn't possible for him to do joint tasks at a level 2 with Minnie at a level 3 or 7 depending on which costume she's in. Mickey has to be at least a level 5 I believe before you can even unlock Minnie. If I ever get the chance to play the game on another device I'm gonna low level the characters and try to work out the exact levels they need to be for thier costume tasks.
