The colorful wheel with popular Sanrio characters.

The video starts with a colorful wheel featuring Sanrio characters, including Kuromi, Hello Kitty, My Melody, Cinnamoroll, and Pompompurin. The text 'Build a Kuromi room with us!' appears.

These items include wallpaper, a couch shaped like Kuromi's head, bat-shaped garlands, headphones, a rug, a side table with a drink, a gift box, balloons, cakes, a DJ set, a disco ball, and finally, animated characters appear in the room. The video ends with a Toca Boca x Hello Kitty and Friends branding screen.
