Mr. Shellby is a character of the day who appeared in Extreme Pokémon!.

Mr. Shellby lives in the town of Eggseter with his wife. They own the Shellby Ranch, and call themselves Pokémon Nesters; people who take care of Pokémon Eggs, as well as the babies after they hatch until they become older to care for themselves.

In addition to working at the Ranch, the Shellbys also help out during the town's annual Extreme Pokémon competition. All competitors in the race must pick up a dummy Egg at the Shellby Ranch and carry it back to the finish line. Ash was successfully able to do this. As a reward for this, and as a thank you from the Shellbys for saving their Pokémon, they gave him an Egg that hatched into a Phanpy.

He was mentioned by Ash and Brock in Hatching a Plan.
