An Inconvenient Tooth is the twelfth episode of Season 4, the 90th overall, and the 3rd of the Still Alive episodes.
The episode begins with Toothy planting a flower. He grabs a box of fertilizer and sprinkles some on the flower, which causes it to grow instantly. Toothy nods in satisfaction and places the box down, which immediately falls over, causing some of the fertilizer to fall into a cup of water, turning it green. Toothy, who is unaware of this, wipes some sweat off his head and drinks the fertilized water, which he immediately spits out, causing the ground to grow a variety of plants and mushrooms. Toothy looks at the plants, disgusted with the taste of the fertilizer when all of a sudden his buckteeth start to grow, so long in fact that they stretch past his chin.
Toothy looks around anxiously for a solution when he notices the shed. He runs inside looking for something to help fix his problem and spots a rasp. Toothy grabs the rasp, lines it up with his teeth, and starts filing his teeth down. He drops the now bloody rasp, in tears over the pain. Despite successfully filing his teeth down to a smaller size, a mirror in his locker reveals that his teeth have grown to bizarre disproportions. Toothy grabs some bolt cutters and with tears filling his eyes, uses the bolt cutters to snap one of his teeth off. He starts to stagger backwards and falls into a wagon.
The wagon moves forward and starts to roll down a hill, with Toothy still inside. As the wagon rolls downward, the curve in Toothy's remaining, overgrown tooth starts to scrape against the ground and it snaps off, followed by the last half of his tooth.
The wagon reaches the bottom of the hill and crashes into a stump. Toothy gets up, dizzy, and realizes his teeth are now normal. Relieved that the pain is finally over, Toothy walks forward happily when all of a sudden a fertilizer delivery truck runs him over. The truck crashes into a tree leaving scattered boxes of fertilizer all over the ground. Popping out of the pile of fertilizer is Lumpy, who was the driver. The episode ends when the fertilizer on one of Lumpy's antlers causes it to grow, the closing iris then closes on Lumpy's large antler, breaking it in half, causing Lumpy to scream in pain.
