The pufferfish ghost effect is Genius! However the rabbit and crow not so much

The pufferfish ghost effect is genius because what killed the pufferfish was the sim eating it, which in turn also killed the sim meaning that they are now bound to each other.

However the same effect with a head of the rabbit or the crow appearing inside stomach of our sim makes very little sense considering that both the crow and the rabbit is still alive. 

The effect looks cool, but i think it could have been used for something else, like say maybe the crystal ball when they are trying to communicate with the dead.

In turn i would have swap the effect for some dust clouds, claw marks and rabbit fur or crow feathers appearing around our ghost some as effects.
