Parabomb

Parabombs (occasionally parsed Para-bombs or Para Bombs and also known as Parachute Bob-ombs) are Bob-ombs with parachutes that appear in several Mario games. They descend slowly from the sky, and once they land, they act like normal Bob-ombs.

Super Mario World
They make their first appearance in Super Mario World, where they descend from the sky and upon landing act like normal Bob-ombs.

Super Mario 64 DS / New Super Mario Bros.
In New Super Mario Bros. and Super Mario 64 DS, there is a minigame called Bob-omb Squad where Para-bombs must be blown-up before they hit guarded flowers.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, Parabombs first appear in World 8-5, where they are one of the many hazards alongside Crowbers and lava geysers that Mario must be careful of. They act identical to their Super Mario World counterparts.

New Super Mario Bros. 2
Para-bombs reappear in New Super Mario Bros. 2, having the same function as in earlier games. They are occasionally shot out of cannons. They appear only in World 2-B and World 6-2.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
Parabombs reappear in New Super Mario Bros. U, acting the same as in previous games. Their only appearance is in Red-Hot Elevator Ride. In New Super Luigi U, Parabombs appear in Current Event and Bowser Jr. Showdown.

Super Mario Maker 2
Parabombs reappear in Super Mario Maker 2 where they can be made by placing a parachute on a Bob-omb. Since they do not appear in Super Mario Bros., Super Mario Bros. 3, and Super Mario 3D World, new sprites were made for them. They can be placed in pipes, Lakitus, Bill Blasters, and Bull's-Eye Blasters. Unlike in New Super Mario Bros. 2, they cannot be placed in cannons.

Hotel Mario
In Hotel Mario, Parabombs can crash into enemies from above. They are similar to their counterparts from Super Mario World, except they can follow Mario and Luigi while falling. If they hit a door, the door closes, making Mario and Luigi's task harder.

Yoshi's Safari
Para Bombs appear as enemies in Yoshi's Safari.

Super Mario RPG: Legend of the Seven Stars
In Super Mario RPG: Legend of the Seven Stars, Booster throws Para-bombs from his train midway up Booster Tower. Touching one prompts a Rob-omb battle. Booster will continue throwing them until he runs out, causing him to leave in annoyance, or the player hides or leaves first, causing him to stop early and leave in dejection.

Yoshi's Story
Para Bombs reappear as enemies in Yoshi's Story, appearing during the fight with Baby Bowser. Yoshi must hit them with eggs to hurt the ghost.

Paper Mario: The Thousand-Year Door
Parabombs make a brief cameo in Paper Mario: The Thousand-Year Door. When Mario and his partner are shot out of the big bomb cannon in the Fahr Outpost, the hatch that holds the Bob-ombs opens up and releases the Bob-ombs. They come down slowly using red parachutes.

Paper Mario: Sticker Star
Parabombs appear in Paper Mario: Sticker Star for the Nintendo 3DS. They are found in Goomba Fortress. The cannons that appear blast the Parabombs from the tower after a Goomba wakes up a sleeping group of Bob-ombs using a trumpet. Once they hit the ground, they attack like normal Bob-ombs. Many Parabombs actually miss the desired area and fall into what seems to be a bottomless pit. After Mario beats the Megasparkle Goomba, Parabombs do not appear anymore. At the rest stop in Bowser's Snow Fort's mine cart ride, Shiny Bob-ombs drop into battle in the form of a Parabomb.

Paper Mario: The Origami King
While regular Parabombs do not appear in Paper Mario: The Origami King, Paper Macho variants of Bob-ombs resemble Parabombs, parachuting in Hotfoot Crater during the section where Mario escapes from the small Paper Macho Goombas. When they land, they chase Mario upon detection and explode after a short period of time.

Super Princess Peach
In Super Princess Peach, Parabombs behave much in the same way as in Super Mario World. There is also a variant of Parabomb named Glad Parabomb.

Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, paper versions of Parabombs appear in the Cannonball Chuck minigame in the arcade. They are seen suspended in mid-air after Mario throws the cannonball with Luigi on it. If the cannonball hits a Parabomb, the minigame ends.

Dr. Mario World
Parabombs appear in Dr. Mario World as assistants. In both stage mode and versus mode, their effect is to transform two objects, mainly viruses, into exploders when the stage starts, where the chance of activation is higher at higher levels (15%, 30%, 45%, 60%, and 80% from levels 1 to 5 respectively). Parabomb assistants are each rewarded after clearing the first area in World 15 and World 28.

Mario Golf: Super Rush
In Mario Golf: Super Rush, Parabombs appear as part of King Bob-omb's Bob-ombs Away Special Shot, where they blow away nearby opponents' golf balls, and in the Battle Golf mode at Super Golf Stadium, where they can appear during the Bob-omb Rush if Rush Countdown is on. When that Rush event takes place, every player will be targeted by multiple Parabombs, with more being targeted for players with a higher rank compared to ones at a lower rank. The Parabombs in this game lack legs and a wind-up key.

Dr. Mario World

 * Stage mode: "Grants 15%/30%/45%/60%/80% chance exploders (2) will appear on stage start."
 * Versus mode: "Grants 15%/30%/45%/60%/80% chance exploders (2) will appear on stage start."

Trivia

 * In the NES version of Yoshi, regular Bob-ombs use Parabomb's Super Mario World sprite, but without the parachute.
 * In the returning microgame Crossing Guard from WarioWare: Twisted!, in the version of WarioWare Gold in the level 3 of this microgame, some bombs landing with a parachute, are similar to a Parabomb.
