I couldn’t verify a specific “drink” action for The Whispering from the info available here, so the safest answer is that the game may not have a drink mechanic at all, or it may be tied to a specific item, bar, or interaction prompt in that experience.

What to try

  • Check your hotbar or inventory for a cup, bottle, or consumable item.
  • Walk up to any bar, counter, or NPC and look for an interaction prompt like E , Click , or Use.
  • Try opening the chat or emote menu if the game uses roleplay-style interactions.
  • If you mean a different Roblox game with a similar name, the drink mechanic could belong to that one instead.

Important note

Some Roblox experiences with “drink” features are 17+ social or roleplay games, while others only include decorative drink items with no real effect. In one Roblox social-game example, drinks are mostly for roleplay and simple effects rather than core gameplay.

Best next step

If you want, I can help you figure it out based on the exact game link or the exact title shown in Roblox.
