Lava Bubble (blue)

Lava Bouncers are invincible enemies that appear in Super Mario Galaxy. They look like Podoboos but are blue and may be related. They first appear when King Kaliente shoots them in the Good Egg Galaxy. They are unleashed in the middle of the battle once Mario knocks his crown off after the second time Mario hits him. They make the battle more difficult, bouncing around the Magma Planet and hurting Mario as he battles the colossal boss. They appear while fighting King Kaliente in Bowser Jr.'s Lava Reactor, but they also appear before the boss. Finally, they appear in the Melty Molten Galaxy, guarding a Silver Star in 'Burning Tide'. They seem to closely resemble Brrr Bits. The only way to kill them is to shoot Star Bits at them.
