They first appear in the New Super Mario Bros. DS Longplay where after the Phone Shark's defeat, they reveal themselves to be the true main antagonists.

Phillip and Kelly are currently planning their next attack.

- In an interview with The RPG Gamer on April 7 2015, He stated that Phillip and Kelly originally lived with their parents outside the Mushroom Kingdom and were quite nice (this was before being babysat by the teenage girls), and they were classmates of Henry and Samantha in the Mushroom Kingdom preschool. They were friends with them for about 2 days until the Bombs did something very bad Henry and Samantha liked this but accidentally told a teacher (Princess Peach) and both Phillip and Kelly were sent home for the day. Something inside the Bombs changed that night and they were filled with pure anger over their betrayal which started their evil legacy. They tried getting revenge on Henry and Samantha by trying to humiliate them but the students didn't believe them and this left Phillip and Kelly Bomb in a very bad mood and made many attempts to sabotage Henry and Samantha's paintings and stuff just leading the Bombs to getting trouble and being sent home. Finally, they literally latched onto Henry and Samantha and jumped them causing them to scream out for a teacher then Peach arrives onto the scene and takes them in to her room, calls their parents and hereby expels both Phillip and Kelly Bomb. They never forgot the incident nor did they forgive Henry and Samantha for any of it. Henry and Samantha apologized a few times back in 2011 when they met the Bombs in their travels which resulted in Phillip and Kelly giving them dirty looks and swearing that them and saying that they'll get their revenge. Which they did 3 years later but it once again failed. At the time the NSMB Longplay was their only appearance.
