The Steal An Egg Dr Scramble storyline ends with Dr. Scramble’s Revenge, listed for September 26 at 15:00 UTC to September 27 at 16:00 UTC. The official listing says Dr. Scramble now targets Ben after Ben broke his control over Sammy, and calls it the final showdown. The listing itself does not publish rewards, boss health or an entry requirement; guides published after launch describe a Mech boss fight, summarized below with their sources.
Open the official Roblox event. We checked the listing and its artwork on September 26, 2026 at about 05:40 UTC. The drone, shop and vault details below come from dated public guides for the week-long event that began September 19; they are not our own gameplay test.

These rows convert one published window; they are not regional releases. The exact timestamps are 2026-09-26T15:00:17.354Z and 2026-09-27T16:00:17.354Z, rounded here to the minute. The window is about 25 hours, one hour longer than the Light vs Darkness listing.
How the Steal An Egg Dr Scramble drones work
Three public guides published between September 21 and 25 describe the same loop for the September 19 event:
- Wave timing: drones arrive every 30 minutes, on the hour and half hour, and each wave lasts about five minutes.
- Where to look: drones appear from Abyss Ocean onward, including the later biomes. One guide reports that spawns are separate for each player.
- Fighting: each bat hit removes one drone HP. Guides list 3 HP, 5 HP and 10 HP drones.
- Samples: defeated drones drop Samples, the event currency. AllThingsHow reports about 22, 65 and 165 Samples for the three drone sizes.
Treat the Sample amounts as one outlet’s observation, not a guaranteed drop table. The wave schedule is consistent across the guides we read.
Experiment Shop prices
Two independent guides (AllThingsHow, September 24, and Timesaver, updated September 25) list identical Sample prices:
| Item | Reported price | Reported limit or effect |
|---|---|---|
| Experiment #001 Egg | 6,500 Samples | One per player |
| Nibbles #013 Egg | 2,950 Samples | Three per player |
| Scrambled Mutation | 475 Samples | Single-use; apply chance disputed |
| 2x Cash Booster | 275 Samples | 10 minutes |
| 1.25x Speed Booster | 375 Samples | 5 minutes |
| 2x Treadmill Booster | 375 Samples | 10 minutes |
The Scrambled Mutation chance is not settled. Two guides say roughly 10% per use, while TechWiser says 1%. We do not publish an expected-cost calculation from either figure. Read the in-game shop text before spending, and see our mutations page for how we handle unverified consumable effects.
Nibbles and the five Vault Parts
The event’s secret mission starts with Nibbles, also called Experiment #013:
- Travel to Abyss Ocean, between Prehistoric and Volcano.
- Find the cave entrance on the left side of the rock wall and interact to enter.
- Talk to Nibbles, the green mouse beside the broken machine, to start the vault quest.
- Collect Lost Part 1 in Prehistoric, behind the bush near the sleeping T-Rex.
- Collect Lost Part 2 high inside the Volcano structure.
- Get Drone Parts 3–5 as random drops from Dr. Scramble drones during waves.
- Return to Nibbles with all five parts to open the Stolen Experiment Vault.
The vault reward reported by several guides is The Scrambler, a limited green bat. Timesaver says it knocks back other players when it hits them. No guide we read published a damage figure. Drone Part drops are chance-based, so the number of waves you need varies.
What the Revenge listing adds: the Mech boss
The September 26 listing is a follow-up to the drone event, not a copy of it. Its artwork shows Dr. Scramble in a green lab beside a NEXT TARGET screen with a masked rabbit, which fits the story text about Ben. The “something much bigger” is a Mech, according to two guides published after launch: TechWiser (September 26) and Bloxodes (September 27), both read September 27 at about 07:30 UTC. We did not play the fight ourselves.
What both guides agree on:
- Spawn timing: the Steal An Egg Dr Scramble Mech fight opens about every 30 minutes during the listing window.
- Fight flow: damage the Mech with your bat, lead the exposed core or Dr. Scramble to a blue tower so it is stunned, attack again, then chase Dr. Scramble and land three hits to finish.
- Rewards: each win pays Samples and progress on a Boss Mastery track. Both name Pink Dragon Experiment #010, an Eternal pet, as the top reward.
Details reported by only one guide, not confirmed by a second source:
| Detail | Reported by | Figure |
|---|---|---|
| Mech health | Bloxodes | 13,300 HP over three phases |
| Samples per win | TechWiser | 1,750 when solo; also scales with damage |
| Mastery milestones | Bloxodes | 90 wins: Biohazard Egg and Scrambled Unstable Egg; 100 wins: Pink Dragon Experiment #010 |
| Mastery size | TechWiser | 22 mastery levels |
| Fight location | TechWiser | Portal in the Titan Temple biome |
The two mastery descriptions use different units, wins versus levels, so we do not convert one into the other. Bloxodes also reports a new Dr. Scramble’s Lab in the lobby, where you hand in three requested eggs for a chance at event pets, and a Robux-only Extinction Egg on sale until October 10. Neither has a second source yet, so we list no odds or prices here. Check the in-game text before you grind or spend.
Preparing without guessing
If you are new, the beginner route covers hatching, pet income and Speed. Drones appear from Abyss Ocean onward, so progress through the earlier zones matters more than any single booster. The Speed planner works with a target you read in game; no event requirement is prefilled.
A 10-minute booster only helps while you are actively playing. Compare boosters with the permanent game passes using the displayed effect, and check the Egg Index for how experiment eggs fit the wider egg list.
Frequently asked questions
Is Dr. Scramble’s Revenge the same as the September 19 event?
No. Guides describe the September 19 drone event as Update 5, running until September 26. The Revenge listing has its own event ID, 6472065313709097739, and its own September 26–27 window. The earlier Light vs Darkness preview is a separate September 12–13 listing.
Does the listing guarantee rewards?
No. The official text describes the story and timing only. The Mech boss, Samples, Boss Mastery and the Pink Dragon Experiment #010 reward come from two dated third-party guides, not from the Roblox record, and the kill counts differ between them.
How often does the Steal An Egg Dr Scramble Mech spawn?
Both guides we read say about every 30 minutes while the listing is live. The window closes September 27 at 16:00 UTC; after that, the fight may no longer appear.
Are there codes for the Dr Scramble event?
The checked listing and game description contain no code string. The codes status page explains why we do not list guessed codes. For the correct game and developer group, use official links.
