From Creatures Wikia
The Norn Nanny is an Agent created by Ghosthande. Similar to the Electronic Butler, the Norn Nanny will vend food whenever there are hungry Norns around it. However, unlike the Electronic Butler, the Norn Nanny can be made to follow a designated Creature around the ship, even between metarooms, in addition to remaining stationary in one position. It also resembles a blue-tinted Cuttlefish.
