The Skirty cheat is a registry edit that, in Creatures version 1.0.2 and above, different from the Doctor cheat purely because it opens world.sfc by default. The Skirty cheat allows the user to switch worlds, pick up creatures and scroll all around Albia. In Doctor mode, Creatures does NOT autosave. Use with caution, with either Gordnorn and Rhodent's BoBCoB tool or Alexander Laemmle's BORG utility.
This cheat can be applied manually in the same way as the Doctor cheat. In The Albian Years version, in Windows Vista and above, regedit can be used to change the "Privileges" key in HKEY_CURRENT_USER/Software/Gameware Development/Creatures/1.0 from "User" to "Skirty".
