How to Get Yellow Knuckles in Prison Pump (Roblox)

To get the Yellow Knuckles (also called Yellow Brass Knuckles) in Prison Pump on Roblox, you mainly get them by using a promo/secret code in the item shop rather than earning them through normal gameplay.

Quick Answer

  • Main method: Use the code FLAVA77Y in the item shop to receive the yellow knuckles weapon.
  • Saw references in TikTok and YouTube videos that specifically mention this code for “Prison Escape II / Prison Pump” and the yellow knuckles.

Step-by-Step: Unlocking Yellow Knuckles

  1. Open Prison Pump on Roblox.

  2. Go to the Item Shop (where you buy weapons, gear, and upgrades).

  3. Look for the promo code / secret code input field.

  4. Enter the code:
    FLAVA77Y
    and claim the reward.

  5. The Yellow Knuckles should appear in your inventory or be directly usable as a weapon.

Other Ways Players Mention

From forum-style discussions and video titles, there are also:

  • References to “Gold Knuckles” and “Neon Knuckles” as separate items, suggesting different colors/versions may be tied to different codes or events.
  • Some videos show players going from “noob to pro/shredded” and experimenting with different gear, which often includes knuckle variants, but the yellow version specifically is linked to the FLAVA77Y code in the available results.

If FLAVA77Y doesn’t work anymore (codes can expire), check:

  • Recent Prison Pump promo code videos on YouTube.
  • TikTok posts with “yellow knuckles prison pump” to see if a new code has been posted by creators.
