Mushroom Kingdom Create-A-Card (holiday)
From the Super Mario Wiki
Mushroom Kingdom Create-A-Card, referred to as Nintendo Custom Card Creator in the title of its web page, is an activity on the Play Nintendo website in which users can design custom holiday greeting cards with Mario-themed decorations. It can only be used on desktop and tablet devices. A regular, non-holiday version of this activity is also available on the website.
The user can add a background and apply greetings, characters and items from the Mario franchise onto a canvas. There is a "clear" button which can be used to reset the card and a "randomize" button which can be used to generate a predetermined card design. On a different screen, the user can compose their own message, which will accompany the card's cover picture. To review the card, the user must click "I'm done!" They can then choose to create another card (which will erase the current one) or download the current card in PDF and JPG formats.
Greetings, characters and items can be resized.
The following compositions can appear when picking "Randomize".
