What I'd really like to see for a wikia is something that makes people want to actually watch the show. I've seen pages written on the Foster's episode guide things that made me go "urgh" because all those did were list the details in flat, monotonic form, and it told me EVERYTHING. If the episodes or shorts have surprise endings I rather not have them revealed, like in "Truth or Stare", the person who wrote the blurb gave it away that Mac was staring down a cardboard Bloo and I totally didn't find the short that interesting afterwards cos I knew what was going to happen.
So, just my opinion, but if anyone is going to write an episode guide or a blurb or something, don't completely give everything away.
Another thing that would be interesting would be a list of merchandise produced (I had no idea they were doing comics nor the range of figurines produced until I came here, and when I saw the scans/photos I got really high.) or a list of all the minor characters, or just mere pictures, if any data of them is given at all. I'm obsessed with minor characters, like Sharkhead and Purple from "Bloo's the Boss" or Imaginary Man and Nemesis from "Challenge of the Imaginary Friends", stuff like that. If it helps I can take screencaps or something (though since Sparky already has an entire database I don't think I'd be of any help in this area >>; )
I'm not sure if this would be useful/of any point, but would a trivia page fit in the wikia somewhere? I was rewatching House of Bloo's when I noticed stuff like continuity errors, such as Scissors being more or less sized like a pair of scissors now; when he was introduced he was nearly as big as Frankie. Jackie Khones as well, was about Coco's size.
...that probably wasn't a lot of help, was it. ._.
