Emmet was attending his duties around the station with his signature muppet-like smile as he marched around the station's premises.

"Follow the schedule. Everybody smile!"

He'd cheerfully call-out, both arms behind his back as his eyes followed passengers boarding the subway. Soon, he turned his attention to you.

"Hello. I am Emmet. You know me, yes? You were verrry quiet while staring at me."

Emmet pointed out before he went silent, sounding mischievous yet playful.
