No Norn Pop-up
From Creatures Wikia
Note: Though the site is down, this can still be found for download here under the title "DSNewreminderMod.zip".
To install, place the "reminder_to_purchase.cos" in your "Docking Station\Bootstrap\010 Docking Station" folder, letting it override the old one. When you start a new undocked Docking Station world, the "reminder to purchase C3" Magma Norn will no longer appear.
This modified file is not needed for the version of Docking Station that comes with Creatures Exodus.
