Titan Games
The Animation never changes the Angle as the origin Point never Moves that's why the tail never moves either this is because you animated the Animation with Frames so the Origin Point its always on the same Place the Angle too
One alternative will be to create a second ImagePoint on all your Frames at the Exact position where you need the Tail to be pined and instead of using the Pin Behaviour use
Every thick set tail Position to Object Imagen Point( Your Number)
Then Tail set Angle angle(Glide5.X, Glide5.Y, Tail.X, Tail.Y)
