From the Super Mario Wiki
Ads keep the MarioWiki independent and free :)
The level is very similar to its New Super Mario Bros. U counterpart. The level starts out on a raft on lava which cannot hold more than four entities not counting Luigi or other players. However, there is a poisonous fog following Luigi from the back. As the level name suggests, there are Magmaws riddled along the lava. There are various enemies to slow the raft down. After a few enemies and expanding blocks, the player finds the Flagpole.
