Mole in the City is an irregular episode in the Happy Tree Friends series.
At night, in the city, The Mole gets off an elevator on the top floor of a tall building. He walks to an office door and removes his mole from his face, placing it on the doorknob. The mole blinks red and lets off a small explosion, blowing off the doorknob and opening the door. He opens a filing cabinet and begins taking photos of some files, while a mysterious figure watches him from the rooftop of a nearby building. When he is done, The Mole places his camera in a briefcase and turns to leave.
He accidentally steps on a security laser, setting of an alarm. The Mole runs to the window in the office, but accidentally hits the wall and stumbles out of the window in a daze. The falling glass shards cut a balloon vendor on the sidewalk below to pieces, before he can give a balloon to an eager child. As the balloons float upwards, The Mole grabs them to stop his fall. This temporarily lifts him in the air while his stalker, a rat in a trenchcoat, watches him through a set of binoculars. The Mole floats to the ground and gives the balloons to the crying child, who begins floating upwards.
The Mole then turns around to find himself face to face with his enemy, The Rat. The Mole takes out his white cane and twirls it around, ready to attack. He places the briefcase down and strikes an attack stance, but, unbeknownst to him, he is facing the wrong direction. The Rat takes the briefcase and runs off, jumping into a giant hamster ball and rolling away.
The Mole holds his cane up and fires a grappling hook out of it. The hook attaches to the hamster ball, pulling The Mole up to it as it continues rolling. The ball bounces up when The Mole's body creates a bump and they fly into a mousetrap factory. The rat wakes up, having fallen out of the ball, and finds a mousetrap clamped down on his nose. To make matters worse, a giant mousetrap has shut across his torso.
He sees The Mole's briefcase in the moonlight and begins dragging his body toward it. Unfortunately for him, the giant mousetrap remains where it is, causing The Rat's body to split in half, held together only by his spinal cord. He reaches the briefcase and opens it, finding nine moles inside which begin blinking red. Outside the factory, The Mole walks off with his briefcase while the factory blows up behind him. He replaces the mole on his face, which begins blinking red.
