Keep the Door Locked Rat Buster Badge

What Rat Buster confirms

Rat Buster is one of the clearest optional badges in Keep the Door Locked. The official description is short and concrete: Hit the pizza rat with a baseball bat. That confirms three facts and almost nothing else: a pizza rat exists, a baseball bat exists, and the badge awards when those two meet in a successful hit.

Public awards sit in the low thousands with a tiny win-rate percentage in recent Roblox snapshots — rare, but far more common than Ending 4 (dozens of awards) or Blood Money (single digits). Treat Rat Buster as a focused item hunt, not as an ultra-mythical Easter egg like Juan.

This page pairs with Hidden Badges, Controls, Visitors Guide, and the Badge Tracker. Do not confuse Rat Buster with Kindness, Dream Room tourism, or ending routes.

Keep the Door Locked anomaly and room-threat footage

Prepare the room before you hunt

A bat is useless if Door Breaker or a window stage 3 panic ends the night. Stabilize first:

1. Practice How to Play and Camera and Door Decisions.
2. Know Survive the Door Breaker and Window Anomaly responses.
3. Keep Common Mistakes habits out of the hunt — especially opening before looking.

Dedicate one research session to Rat Buster only. Mixing pizza-rat hunting with Ending 4 trust choices or Blood Money grinding produces noisy deaths and useless notes.

Find the tools, then the target

Search methodically. Learn every ordinary interaction point in the hotel room so a new prop stands out. When you obtain or notice a baseball bat:

• Read the equip / use prompt carefully (Controls).
• Confirm the item is ready before you chase movement on the floor or near food props.
• Do not swing randomly at furniture; wait for a clear pizza-rat target.

When a pizza rat appears, commit once: aim the bat interaction at the rat and follow the prompt. Panic spam can miss the hit window or pull you into an unrelated anomaly. If the rat flees, note the room state instead of inventing a “guaranteed corner” map that no badge text supports.

What the badge does not prove

Rat Buster does not confirm:

• a fixed day number or server timer;
• a universal spawn coordinate;
• that the rat is always hostile or always cute;
• a cash payout, ending unlock, or Kindness link;
• that an executor “auto bat” script is safe or required.

Reject YouTube titles that sell a one-click Rat Buster with a loadstring. The Scripts hub explains why auto-fix tools risk bans and malware. Promo codes help cash and tokens; they do not spawn the pizza rat.

Separate Rat Buster from Kindness and Juan

Kindness is a help-and-return narrative (Kindness Badge). Helping a rat-related visitor — if one appears — is not automatically Rat Buster unless the bat hit lands. Juan and What the Dog Doin’ remain ultra-rare Easter eggs with vague wording; do not force the pizza rat into those stories without evidence.

If your balance changes after a rat event, log money separately for Blood Money research. Causation needs repeats, not one coincidence.

Logging a clean attempt

For every session write:

• whether a bat was available and how you obtained or noticed it;
• when and where the pizza rat appeared;
• whether the hit registered and whether Rat Buster awarded;
• any interrupting anomaly (shadow, hider, toilet, window).

Tick Rat Buster on the Badge Tracker only after the Roblox award. Near-misses stay in notes. Compare rarity expectations with Ending 2 / Ending 4 so you do not quit a viable hunt too early — or waste a ten-day clear chasing a rat while ignoring cameras.

Practical closing loop

Survive first, search second, swing once with intent. Rat Buster is a badge you can plan for because the text names the tools. It is still easy to overclaim. Keep the door locked until the feed is clear, keep the bat ready when the pizza rat shows, and leave fake spawn calendars off this wiki.
