Pipes are a common obstacle and method of transportation in the Mario universe. Some pipes often lead to various places, in which Mario can enter. As SuperMarioGlitchy4's videos are mostly based on the video game Super Mario 64 on the Nintendo 64, several pipes appear sometimes in his videos. They're usually inanimate objects, but in the blooper "Super Mario 64 Bloopers: Problematic Pipe Problems", they appear as living characters, and they have a king called King Pipe.
The pipes exist in several colours, but the most common one is green. The sentient pipes look exactly like the other ones, and are faceless despite being living characters. However, one of them was seen wearing glasses.
- Pipes appears in many bloopers of SMG4, but "Super Mario 64 Bloopers: Mario Quits", "Super Mario 64 Bloopers: Plumber Academy for Idiots" and "Super Mario 64 Bloopers: Problematic Pipe Problems" are the only video in which they appear as living characters.
