Confining Currents is the third level of World 3 in AKR2. It is an auto-scrolling underwater stage.
The level begins with the player having to swim past a path of electreels. The first baby can be found in this section and the first star coin is in between a path of eels in the section.
The next section scrolls upwards and a nighttime block can be found next to the second baby. You have to make your way through a path of dolphins and electric eels in order to earn power-ups and coins. A beautiful sunken pirate ship is shown in the background. The section concludes with the player having to earn a Starman in order to swim past a path of Drill Kills.
The final section introduces you to two paths. The first path has the second star coin and the second has the third baby and a midpoint flag. The screen will then scroll downwards until the screen eventually scrolls to the left. There is the fourth baby there and the third star coin. After a little more scrolling to the right, there will be a pipe. Go through it, and there are a few coins and the endpoint. The whale in the next level is shown in the background.
