It is recommended but not required that you look at Volumes 1-3 first: https://scratch.mit.edu/studios/1349058/ This may not be as great as The Origin of Scratch Cat, but I'm still very proud of this animation. Check out The Origin of Giga: https://scratch.mit.edu/projects/69769446/ and stay tuned for more Scratch Stories!
Love/favorite if you enjoyed it! This the origin of one of the most famous Scratch mascots, Pico. It's the story of what Pico went through leading up to his days being part of Scratch, and how he got where he is today. It's a story of friendship and being grateful for what you have in life. Please watch the entire animation.
