While walking around at Nellis Air Force Base, one may happen upon one or more Mini Boomers (Boomer children) moving about the compound. Usually they can be found in or near the Nellis children's barracks and the Nellis schoolhouse, but occasionally a large group will wander together near Raquel's observation post and the nearby howitzer.
Though they are not named non-player characters, several Mini Boomers have unique dialogue options that can improve or damage the Courier's reputation with the Boomers. Interacting with them will produce several dialogue responses depending which one is spoken to. The children respond as imaginary characters as depicted on skill magazine covers or reference Fallout style adaptation of common children's games and play themes.
- In order to access their positive unique dialogue the Courier must have a Charisma of 7 or more when initiating conversation.
- Also, when starting a conversation with a Charisma of 7 there will be an additional dialogue choice if a rocket souvenir or a dino toy (though not the similar but far more common Dinky the T-Rex souvenir) is in the player's inventory during the conversation, depending upon which child is being spoken to. There is an alternative option to say with Charisma of 7, but it will give less fame.
- The possible negative dialogue choices are available simply by having bubble gum or Psycho (in the case of the Red-Brick Kid) in the player character's inventory, and has no Charisma requirement.
- Once a speech option is chosen in conversation with a particular mini-boomer, that child will no longer offer any further interactive dialogue for the remainder of the game.
- Backing out of the conversation without selecting any special options does not inhibit the player character from speaking to the child at a later time.
- The speech option triggers for the children can be identified as follows:
- ¡La Fantoma! (Girl with blond hair wearing ragamuffin outfit) - toy rocket - radioactive gum
- Boomers and Targets (boy wearing a Vault 34 Boomer outfit) - toy rocket - radioactive gum
- Gate Keeper/Toll Taker (girl wearing junior officer outfit) - toy rocket - radioactive gum
- Mission Control (girl wearing Athlete of the Wastes outfit) - toy rocket - radioactive gum
- Outsider wasteland tales (girl with brown hair wearing ragamuffin outfit) - toy rocket - radioactive gum
- Dino-Boy (boy with dark hair wearing ragamuffin outfit) - dinosaur toy - radioactive gum
- Red-Brick Kid (boy with red hair wearing ragamuffin outfit) - dinosaur toy - psycho
- Two dino toys can be found in the teacher's desk, which has a very easy lock.
