Getting the Cool Hopper from the Snowman challange

That's strange, as its description says "complete a coding challenge". Try checking for new avatars and badges (in profile under badge counts). If that doesn't work, you can send a support request.

I think I've seen comments before that sometimes it takes a day or reloading Khan Academy.  You might try that before sending a support request.

Same hing happened to me here 😔. I also wanted him....
