Level 3 is the longest level by far in the entire game, along with lots of hidden traps to try and kill you. This level introduces the boost, which can be used by pressing B, and will send King K. high into the sky with a large amount of momentum. In this level, much like level 2, it is possible to stay in the air forever, doing a technique calling "pinwheeling." The simpliest way to explain pinwheeling is by having one arm face the player, and having another arm facing forwards, hold forward and jump at the same time to gain height. Do not let go of either, as you will either lose height or momentum. While pinwheeling it may become difficult to see the platforms beneth you, however this is the easiest technique to cross the gaps amongst the asteroids.

After the second coin, you will get onto a straight platform with a coin and 3 boosts at the end of it. Once you have reached this platform, 3 meteors are going to be flung at you. Move forwards slowly to spawn the first meteor, and quickly back up to avoid it. The second and third meteors can be avoided by boosting over them and pinwheeling past.

After collecting the fourth coin, and on the final stretch of the level, multiple Star Wars ships are going to spawn and move toward you in an attempt to knock you off. Simply collect as much boost as you can (max of 5) and jump over each of them as they approach you.

Once the ships have been dodged, the final coin is sitting on a platform above. There is a staircase next to the platform to get up, however these stairs are inconsistent and dangerous, so do not take them. Simply back up, and pinwheel up to the platform, and use a boost if you have to. Just give yourself enough room to gain enough height to get over the platform, and land on it to grab the final Remy coin.
