Doctor Future gave Pocket Designers to Miraitchi and Clulutchi because of their passion for designing.
The twins use their Pocket Designers to design clothes for their friends; their creations then become real so Tamagotchis can wear them. The Pocket Designer can also create clothes that give Tamagotchis the ability to fly. This is important because it helps the twins obtain the Dreambakutchis.
When a Dreambakutchi is found, it will then be stored in the Pocket Designer, much like how Kizunatchi and the Tama Hearts can enter the Tama Profy. The Dreambakutchi will continue to live inside the Pocket Designer, on a small world behind the screen. Miraitchi and Clulutchi can then check on the Dreambakutchis they have collected.
The Pocket Designer is pink and rectangular. The screen is farther on the right side of the toy instead of in the middle, and is surrounded by a black border. On the top left corner is a small, pink heart jewel, and on the bottom left corner is a hole for attaching charms. The slot for the stylus is on the lower right side of the device. There is a pattern of stitches all along the edges of the device.
The toy of the Pocket Designer has the words "TMGC" and "Pocket Designer" engraved on its surface; this does not appear in the anime depiction of the device. The infra-red sensor is on the upper left side of the toy.
Bandai is releasing a toy of this item, called Pen Touch Pocket Designer Notebook. It has a color touch screen and a stylus, much like a Nintendo DS. Users can create their own clothing, accessories, and hairstyles by choosing shape, pattern and color, and send it to the Tamagotchi P's. It will sell for 8,379 Yen.
Users will also be able to buy covers for the toy. There are currently two covers to be released: The original version and a Mezzo Piano version.
- Mezzo Piano is a popular fashion line in Japan that makes clothes for young girls.
