Making a new TADC quiz

I'm planning to make a trivia based The Amazing Digital Circus quiz opposed to the lyrical ones I've been making recently. Out of the main cast (plus other major characters e.g. Caine, Bubble, Gummigoo) which character would you guys like to see a quiz about first?

Also really sorry about originally posting this on my blog instead of here, I'm fairly new to the whole quizmaking and blog thing and I didn't actually realise message boards existed so thanks so much to the people who pointed this out and in the future I will definitely post my questions about opinions here and save longer and more blog appropriate stuff on my blog.

(If I'm doing this wrong, please correct me. Sorry this is my first time using message board)

Thanks for your input, I'm desperately indecisive
