Magmaws are a species of Blarggs that first appeared in Super Mario Galaxy 2.
 Super Mario series
 Super Mario Galaxy 2
In Super Mario Galaxy 2, they are found exclusively in the Melty Monster Galaxy. Magmaws live in lava and attack by opening their mouths and passing through asteroids that the player may be on. They seem to be mostly liquid because small objects such as meteors can pass through their body. Much like their larger counterparts, Magmaarghs, they cannot be defeated.
 New Super Mario Bros. U
Magmaws make an appearance in New Super Mario Bros. U in Princess Peach's Castle. They appear in Magma-River Cruise where they come up from the lava, move towards the player and go back down.
