How to delete the humanoid out of an NPC, without messing it up?

I have an NPC that is just for dialog, it doesn't do anything but serve as a standing player like thing that has a dialog above it. How would I delete the humanoid out of this without making it's body all blocky and gray? As the moment I try to delete the humanoid this happens.

The problem is that CharacterAppearance classes such as Shirt and BodyColors require that a humanoid is present in the model to work. The most simple solution is to simply not delete the humanoid. If you don't want to see the humanoid's name, you can hide it by setting the DisplayDistanceType to None.

To not show the health and name, select Humanoid, go to DisplayDistanceType and select None.
