In Animal Hospital on Roblox, the mouse is typically released by pressing the Exit button in the UI when that screen appears, rather than a special “unlock mouse” key. On PC, most interactions still use the usual Roblox pattern: E for interact and mouse clicks for UI elements like CCTV or prompts.

What to press

  • E for most in-game interactions on PC.
  • Click UI buttons like CCTV feeds, photo prompts, or other menu elements.
  • Exit on the bottom of the screen when an anomaly or prompt uses that button.

If the mouse feels stuck

  • Move your cursor onto the active UI and click the button that appears.
  • If the game is in a forced first-person style moment, Roblox UI buttons can temporarily release mouse lock when they are active.
  • On mobile, use the tap prompts instead of keyboard controls.

Quick answer

If you mean “which button frees the mouse,” the best match is the Exit button when it shows up on-screen, and otherwise the game mostly expects E plus normal mouse clicks for menus.
