  - A *Sprite* component with the bunny image.
  - A *Collision object* component. It has *Type* set to `DYNAMIC`. A sphere *Shape* matching the sprite image is added to the components.
  - A *Script* component that animates the bunny's position and reacts to physics messages when interacting with the trigger.
