The Giant Potion turns a Smiler into a much larger body with a stomp and a crouch. Allies can stand on a crouching Giant to regenerate faster, and the Giant can throw them. The Halloween update on 24 October 2026 reworked the transformation and the stomp. Older notes that gave a 120-second cooldown, a 5-second ragdoll, and a 20-stud radius are from before that rework, so they are not listed as current numbers. Read the in-game log for the new stomp.
Curing Water kills a Giant outright. Do not drink the potion on a route that is about to load Swamp of Sadness. A normal Smiler who touches that water is cured instead.
Where the bottle is
Public servers roll a few stages at a time, so you wait for the right room.
- Lockers: upper floors. A red key opens the side room that holds a green key. The green door is the Giant Potion, and it is also a Tommy Gun door. Whoever opens it can lose the bottle to the next player through the door.
- Headcam: spawn a bomb, blow the cracked wall, use a green key. If you take the Giant Potion, Tommy Guns still in that room despawn.
- Slime Room: hold E for about 3 seconds to spawn a bomb, push it into the cracked wall, then use a green key. Slimes on the platforms split when hit.
- A 2026 potion tour also shows Chained Office and a bomb route from another map, such as Safe Lab, that does not start with a green key. Use the green-key rooms first if you already hold the key.
Only Smilers should drink it. A spring balance note said the bottle itself became Smiler-only, with a short forcefield when a key door that contains one is opened.
Fighting a Giant as a human
The Hatchet is the grab escape that works on Giants, at half of its 4 charges. The Knife does not break a Giant grab. Shotgun knockdowns still matter if you have a shell. The Tommy Gun's 3-second burst is the cleanest delete if you are level 10 and inside 30 studs. When the Giant dies, Smile Coins spill for 3 each. Pick them up before they clip under stairs.
Orange Depressing Light still kills infected players. A Giant who is kited into it does not get a special exception in the light descriptions. Do not stand under the stomp while you check.
