Pages have been made, and YazzyDream even figured out the carny's name is "Sprott" from looking at credits at the end of it. I also saw names of characters not in that short in the credits, and I'm saying that they will be in other shorts in the "Mabel's Album" series as it seems to be since Disney XD Italy uploaded this theater one today https://www.youtube.com/watch?v=N9POdZxMNtE and it is set up the same way, has the same credits as The Petting Zoo (and probably the rest of the set of shorts), and Thompson is in it as he is in the credits. Other characters in the voice credits who have not yet been in the set of shorts are Gideon, (Deputy) Durland, some agent, (Sheriff) Blubs, Bud Gleeful, and "Sassica" which I'm sure must be Pacifica. I tried looking at the international versions page of the wiki but found no Italian section. Looking forward to more of these shorts, as Disney XD Italy seems to be uploading them one a day at this time!
