Korkkiruuvi (Corkscrew) is a compact looping coaster made by Vekoma. For long it was one of the main symbols of the park along with the Dolphins and Näsinneula. The track is very short, so many have said that it's lost some of the former thrill after Tornado was built.

Korkkiruuvi was bought used from the British Clacton Pier. If you know Finnish language, you can check out this paper article from 1987 about Särkänniemi's new "mega coaster".
