Minor Cash Shop & NX items Robot pet does cool animation when being fed

Prior to January 20th update I've never noticed this animation before, but when I feed my robot pet it does an animation. However the animation is not seen on the client on which the pet is being fed.

See video below for demonstration, in the left client I feed the pet, but only the right client can see the animation

 

As of the latest patch this animation no longer shows on either clients =)
