Hence its namesake, the player has to keep moving in this level. At the beginning of the level, Red Yoshi will find many Countdown Platforms, and then after going along them a bit, a Shark Chomp will start chasing the player. Soon after, the player will need to ride a spinning platform to get to some Flatbed Ferries over spikes, where Yoshi will encounter another Shark Chomp. Then the player will need to ride another Flatbed Ferry, then cross a lot of spikes on Countdown Platforms.
The player will then need to cross a bridge over a long gap. At the end of the gap they will be on a large stone area, but then go onto another bridge, which leads to a Flatbed Ferry. The player will continue to go through a winding area full of many Flatbed Ferries. Eventually the player will get to an area with some steps heading up into the next area. After that there will be a castle arena filled with great number of Bandits. After that area the player will need to cross some thorns, after that the player will go up some steps where they will encounter even more Bandits. Not long after, the level will be completed after going down a Warp Pipe.
This level uses the fort/castle background music, despite not being a fort/castle level. It is the only main level in the game to do this, and is one of two levels (excluding the secret levels from the Game Boy Advance remake) with this distinction; the other being the extra level, Poochy Ain't Stupid. However, the last part of the level appears to be in front of a castle, likely to introduce the next level, King Bowser's Castle. The background used in the second scene of this level alludes to Van Gogh's The Starry Night.
