Kabasira

Kabasira (蚊柱) is a badnik in Sonic the Hedgehog CD's Stardust Speedway. It isn't listed in any instruction manual, however it is referred to as "kabasira" in the game's source code. This is a slight misspelling of "kabashira", the Japanese word for mosquito column or swarm. It is a small badnik that shoots out a smoke trail when it travels (and it doesn't travel very far). Just hit it (it will be the non-flashing piece) to destroy it.
