I found out that the creator of the Carristawn map was Theo999. I also figured out who created other maps.
- Peppa Country - Piggabubblyboo456 (First, I thought Brandonmcabee created that map.)
- PaulMap (unusual map) - Marcos19
- Peppatown between America\Europe - Johnny06
- Alman Island - Johnathanmonaghan
- Huntley - Joshuageorge06
- Isla Nubar - Liopleurodons (Why in the world would he create a map that has nothing to do with this wiki?)
- Peppa Pig in South Jakarta - Undhee
- Peppaverse map - Icebloxion
- Cheyenne, Wyoming - InSaNeJOY
How did I know who created these maps? I added these maps onto VisualEditor and I saw their names below the maps.
