In one of the anime episodes, I remember seeing Mr. Mime doing some cleaning for Delia, Ash's mom. If I ever had one of these Pokémon, I would always keep it with me at the kitchen when cooking. If I ever ended up making a mess, it would always be able to help me clean up. Not only that, but with its psychic powers, it would also be able to lend me knowledge on how to cook something—enabling me to make delicious dishes for my family!
I would have a Shuckle, too. I could put fruits into its shell, and within just a few seconds, it would be able to turn them into juices. This would completely eliminate the need for blenders, haha. I'd still have one of those laying around, though, just in case if my Shuckle ever gets sick or anything. I'd probably have a Tropius as well. I won't necessarily have it in my kitchen (since it won't fit), but it would be near the window. Whenever I needed some bananas, I could always put my hand out and grab a few from its neck. (:
