The strip's simple premise featured Sid and his petsnake Slippy. Slippy had the ability to morph into various useful shapes. Sid was also the leader of the "Whizz-Kids" (characters who featured in the Whizzer section of the comic, as opposed to the "Chip-ites") and, bar the first issue (in which he appeared on the front cover of Chips, usually Shiner's job) he appeared on the front cover of the comic until the mid-1980s.
The strip survived the merger with Buster in 1990. Though the strip was no longer the leader of the Whizz-Kids, it still appeared in Buster until the comic's last issue at the beginning of 2000. As with all other strips that were still being published, it had by that time become a reprint.
In Germany, the strip was called Twinky & Twist and occupied the last page of Felix magazine in the second half of the 1970s.
