Kids set complete.

What Jason said. A few weeks ago, Milhouse was the only kid available. Now, Martin was added. I wonder when the new content will be released.

so,those of us who started playing early and completed the set when milhouse was the only kid god the advantage over others who will play and have to unlock milhouse,martin,etc to get it? hah ^^

What Jason said.

Originally when the game came out, Milhouse was the only kid & I completed the set then. Now with Martin, I completed it as well. As they add new content, the sets will continue to grow.

The other one was when Mr. Burns & Hans Scorpio were the only villains. Snake didn't have a set, he was just random. Once they released the game back into the app stor for everyone in August, Snake was added to the Villains

I'm sure one of the sets that will change down the road as they add more characters, will be the one with Hans Moleman & Squeaky Voiced Teen. I would imagine that's where they will add all Premium characters that wouldn't normally fit into any other category set. Radioactive Man, Very Tall Man, Jasper Beardly, Crazy Old Man, Capital City Goofball, The Devil, etc...

crazy old man hahahah oh god yes,completely forgot that character
