Puker

Seen in the 7th Episode Pixel Brains Playthrough of Super Mario Bros. 3, Ron ends up encountering these enemies and they throw up spike balls to throw at our heroes, hence their name. When Ron dies to a puker, another looks as if he's choking on his spike ball, and Steve loses it.

Before episode 13 of their Super Mario Bros 3. Playthrough, Steve knew them as the "Lip turtles" but Ron sticks with Pukers.
