The client want 4 pigs that display different emotions and personality.

Personalities are :

Ping-Pong-Pig is overwhelmed, busy, frantic eyes, maybe sweating.

Party-Pooper-Pig is sad but not crying, and tired.

Parked-Pig is bored, shrugging like couldn't care less, daydreaming.

Pile-it-on-Pig is strong but irritated, doing it all, overworked and still going, gritting its teeth, just keeps going and going.
