I've been tracking down as much SanrioTown content as I can find to archive and this one caught my attention as this game looked unique from other games on the site. When looking into this game though, I found out that this game has pretty much no additional information, download links, screenshots or videos of the game besides what was shown on the SanrioTown Blog around Mid-November 2007.
From the description and the only two screenshots of it on the English blog, it seemed to be a 3D kart racing game consisting of three tracks to race on. Each track would have to be unlocked after completing the first track, the player as one chance to beat it or the game ends. Once the player has completed all the tracks, they would be ranked on a top five list against the other racers.
The game's roster consists of Hello Kitty, Badtz-Maru, Dear Daniel and Keroppi. Each character has their own stats with strengths and weaknesses.
On the Chinese version of the blog, there were some additional screenshots of the 3D models used in the render image.
