Can you guys help me?

Ok I just went through maybe 50 posts here and everyone seems nice so I’m giving this a go. I’m so sorry if I’m not supposed to post questions like this. But my little guy has autism and he’s absolutely sprunki obsessed. He discovered it when his teenage bro was taking a coding class and now his whole life is sprunki. While i see the games and content for hours on end, i don’t know how to explain sprunki other than it’s a music game and there’s some really fun content and also some wild stuff we have to occasionally block if too adult. I read the wiki but it’s kind of light on info beyond the music game part. And you guys are making all these cool sprunkis and their stories and I just want to know more! Are you all coders and artists (or both obvs)? Are there more legitimate sprunki sources/websites? Stuff I should avoid? I bought him everything sprunki I can find on amazon. Is that bad for any reason? Like copyright or something? Sky and Simon and Oren are his faves usually but he shows love for all of them. He draws sprunkis all the time, everyday. We are playing sprunki on Fortnite rn. Thank you in advance!
