There are definitely some animated characters/robotics/puppets... the zombie dog, the enormous clown face, some of the creatures in Nevermore, etc...
They generally pulse, even if it means increasing the line to 45 minutes. It makes for a far superior house experience and often the pulsed group will separate within a minute, leaving you and your party completely alone.
I've just finished/published my review of the haunted houses, and needless to say I was impressed.
