To achieve fluid movement, the model requires a complex skeleton (armature). This includes IK (Inverse Kinematics) for limbs and shape keys or facial rigs for expressive lip-syncing and eye movements.

To mimic the "bouncy" or fluid look seen in the video, artists use cloth and soft-body physics simulations within their 3D software. 3. Animation Workflow

Most of these animations are hand-keyed rather than motion-captured to maintain an "exaggerated" anime feel.

Dynamic camera angles (low shots, close-ups) are used to emphasize the scale and the "Halloween" atmosphere. 4. Rendering and Compositing

If you are looking to "produce" or recreate a similar animation, 1. Pre-Production & Character Design

Software like Adobe After Effects is used to add glows, color grading, and environmental effects (like the foggy atmosphere in the video). 5. Sourcing or Studying the Original
