Dash & Spin Chousoku Sonic (ダッシュ&スピン 超速ソニック) is a two volume manga anthology of short stories and omakes that appeared on a magazine called Coro Coro Comics, published by Shogakukan. It follows the Kodomo genre, as it was mainly targeted at children, with standalone and non-episodic stories, which are quite moralistic but also very slapstick. The stories were authored by Kenji Terada and illustrated by Santa Harukaze.
It is unknown when the first volume was published besides a tentative late 2001 date, but the second was definetly published in February 2005. The manga was never published outside of Japan nor in any language other than Japanese. However, some scans eventually made it to the internet and some fan translations were attempted, though never completed.
