DNA Strands

DNA strands (a.k.a. Helixes) are an obstacle encountered in Checkpoint 1, Zen Mode, and Local Multiplayer modes. They take the shape of a DNA strand, hence the name.

There are six main types encountered in the Checkpoint 1. Three are dangerous, and the others are not. There are also some encountered on the side. These are not dangerous.

In the Local Multiplayer, there are two of them seen at any one time. They are dangerous to each player and so must be smashed.
