Gardening gnome
The Gardening Gnome is an NPC that Sims can create by casting the Enchant spell on a gnome made with the Woodworking Table. Gardening gnomes will water plants and tend to any gardens a Sim has - until the spell wears off or a magical Sim solidifies the gnome. If there is a nectar press on the lot, gnomes will occasionally swim around in it and then comically stagger around drunk for a few minutes.
A dragon may play tag with a gnome. If Unleashed is installed, dogs and cats may do so as well.
