2.there was no hair on the tail, added

1.update-fixed weights and finger.to prevent the legs from floating during the animation, set the skeleton settings retarget as in the screenshot

you can customize the colors(see the video) there are additional bones in the mouth and tail, the tail is simulated by physics, after retargeting I recommend to correct the neck and head manually in the animation because the neck and head are in a different position. the pose doesn't match the mannequin. there are mouth animations to mix with the main ones

animations in the video render are not included in the asset
