Dancing Hoppe-chan is a toy by Takara Tomy, resembling a blob that can tilt itself back and play eight tunes.
It comes in five color variations, including blue with a pink bow, purple with a black bow, pink with a red bow, black with cat ears and red bow, and white with rabbit ears and a chrome pink bow. The rabbit version was sold in a limited edition set, with a pink Singing Hoppe-chan toy.
Each Hoppe-chan plays a different song when they are the main vocalist of a group dance. The purple one and white one play "Fashion Monster" by Kyari Pamyu Pamyu, the pink one plays "Heavy Rotation" by AKB48, and the blue one and black one play "A・RA・SHI" by Arashi. They play songs like them, using a series of beeps.
A limited edition toy set featuring a Singing Hoppe-chan and a Dancing Hoppe-chan toy was sold. It was called "Cat Ears & Bunny Ears Hoppe-chan Very Rare Ribbon Set" (ネコ耳&ウサ耳ほっぺちゃん激レアリボンセット).
The Singing Hoppe-chan toy in this set is a pink blob with cat ears, a chrome red bow, and shiny cheeks; a version of it that was sold separately has a red bow that is not shiny, and its cheeks also aren't shiny. Unlike Dancing Hoppe-chan, it glows instead of moving.
According to the back of the box, the rabbit Hoppe-chan is supposed to play "Fashion Monster".
