Mushroom Kingdom Create-A-Card, referred to as Custom Nintendo Greeting Card Creator in the name of its web page, is an activity on the Play Nintendo website.[1] It is a tool to create greeting cards using 2D artwork from the Mario franchise, and is only available to use on desktop and tablet devices. A holiday variant also exists.
With this tool, the user can design a card using elements from the Mario series. The user can choose from different backgrounds and place greetings, characters, or items. A clear button exists to reset the card. A "randomize" button is used to choose a predetermined card design. The user can also add their own message below the card, with the choice to change the text color. Once the user is finished, they can download the card as both a printable PDF and a JPG image.
