Ambulance is a term used to refer to any artifact or other normally inanimate object which becomes animate. At this point it is considered "ambulant", and generally is able to reproduce, move, interact, and otherwise behave as a living creature.

Ambulant Furniture is the most common and widely known form of ambulance, however buildings, clothing, and weapons are all commonplace. It tends to occur to objects one has a strong attachment to for a prolonged period of time. This creates an inherent risk in holding on to one's most tried and true artifacts or keepsakes as they may eventually become ambulant and, in many cases, unruly or unusable. It also encourages one to frequently get rid of old belongings in favor of newer ones and fuels Nodd's ongoing search for novelty. The behavior is ensconced and encouraged each and every turn by The Pruning.

Most buildings in Nodd are not literally built but those that are can achieve ambulance if occupied and cared for long enough.
