'''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.


==Bloated Bob-omb==
The bloated Bob-omb is the state when the Bob-omb gets bigger, right before exploding. Usually, this Bob-omb explodes. But if you grab it right before the explosion, it will be delayed for 12 frames. Note that if the explosion is early (by throwing the Bob-omb on the ground) It won't explode until the timer expires.
The explosion is delayed, but the Bob-omb stays big, which means that its hitbox is bigger, enough to push Mario backwards.
===Maintaining a Bloated State===
After grabbing the bloated Bob-omb, you have to walk, then the Bob-omb will start exploding again, then you have to re-grab the Bob-omb. During these small frames of walking, you will be able to turn.

Another way of keeping it is by holding it [[Hands-free]]. You will be able to jump, jumpkick, double jump, triple jump, and ground pound. You can't turn except if you have a [[Wing Cap]], where you will be able to fly while being pushed backwards.

===Hands-free Teleported Bloated Bob-omb===
If you teleport while holding a Bob-omb [[Hands-free]], This Bob-omb will disappear. But if you go close to the first teleporter or if you teleport back, the Bob-omb will appear in front of you, giving you backwards momentum while keeping almost every movement. You can grab that Bob-omb by diving or punching. Kicking will cancel the momentum.

===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.]

==Interaction with walls==
The game first adds the speed to the current position and uses that point in the collision calculations. The algorithm will push 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 bob-omb'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. This occurs before the Bob-omb's actual movement step, so then it moves a 2nd time before the frame ends. Thus, when Bob-ombs touch a wall, their speed is effectively doubled.

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.

==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.
