Hi thank you for your videos. My son loves them. He asks: “Can you please make a manatee, the cow of the sea, blue ringed octopus, mimic octopus and colossal squid”. Regards on behalf of my son, Eddie.
No, all the pieces are in the set. I imported the parts list of the official Lego set into Studio when I designed the model, I built the model from my own set and my submitted parts list was approved by Rebrickable when I posted the model.
