 '''Bob-ombs'''<!--or '''Bombombs'''--> are enemies in SM64. When they see Mario, their fuse lights and they start chasing him. After their fuse ends, they explode, creating an explosion object.

-Tyler, in discord: "@Kaztalek and others who were thinking there were a couple speed vectors being added were basically spot on. When testing for wall collisions on Bob-ombs, the game first adds the speed to the current position and uses that point in the collision calculations. The algorithm pushes the bob-omb outward from the wall if a collision occurs, so if it's already against the wall it effectively adds the component of the bobomb's speed that's tangent to the wall. Regardless of whether a collision occurs or not, the Bob-omb's position is incremented by its speed at a later point as well. Finally, since the point used for the collision calculation is only written to the Bob-omb's position if a collision occurs, the double speed increment doesn't happen in the open field."
+The following courses have Bob-ombs:
-Basically, Bob-ombs always check for wall collision before moving. If they do collide with a wall hitbox, then the Bob-omb's position is incremented and pushed away by the wall.

-This is before the Bob-omb's actual movement step occurs, so then it moves a 2nd time before the frame ends. Thus, when Bob-ombs touch a wall, their speed is effectively doubled.

 ===Uses===
 This trick is used frequently in the [[A Button Challenge]], but also generally for clipping through walls, such as in [https://www.youtube.com/watch?v=28PT7HZWaHI the Chain Chomp's Gate clip.]

+==Supersaturated Bob-omb==
+A supersaturated Bob-omb is a Bob-omb whose fuse timer has overflowed, which vastly delays its explosion. Because the underlying glitch takes 828 days (2.3 years) to execute, it is the most time-consuming glitch in the game.
