Imagine if she was Queen Viola. Also you were right about the mother theory it was confirmed in the piggy survival manual. I couldn’t find the video to comment that on lol.
I serched up Lucella and it said its in London so we are from london and on peppa pig shes brittish and got a little London ancient so mini said its in uk because peppa pig is from there.
The city map and safe place doesn't, since they take place in a different city. But the house, station, gallery, Forest, school, hospital, metro, store, (maybe carnival) all take place in lucella
It would make sense it would take in the UK because Peppa Pig is a British Children TV show And the Piggy characters are Just older Peppa Pig characters.
