The Rainbow Drilla is a Cosmic-tier pet in Steal an Egg that earns 137M/s, and it does not spawn in any biome. It comes out of a Limited Drill Egg, and the only way to hold a Limited Drill Egg is to finish in the top three of the Monster Obby race that an admin launches during an Admin Abuse session.
Quick answer: Join a public server before Admin Abuse begins, enter the Monster Obby portal when the admin opens it, and rack up as many obby wins as possible. Place in the top three on the win leaderboard and you receive a Limited Drill Egg, which hatches the Rainbow Drilla.
Admin Abuse window: when the Monster Obby can appear
Nothing here is farmable on your own schedule. The Monster Obby is triggered live by a developer, and it only runs inside the weekly Admin Abuse window, which lands on Saturdays right before the week’s update goes live. The session itself lasts roughly 30 to 60 minutes, and the obby is one segment inside it.
| Region | Saturday start time |
|---|---|
| UTC | 3:00 PM |
| US Pacific (PDT) | 8:00 AM |
| US Central (CDT) | 10:00 AM |
| US Eastern (EDT) | 11:00 AM |
| UK (BST) | 4:00 PM |
| Central Europe (CEST) | 5:00 PM |
| India (IST) | 8:30 PM |
| East Australia (AEST) | 1:00 AM (Sunday) |
The most recent session ran on Saturday, August 29, alongside the Titan Temple content drop. No date is officially confirmed for the session after that beyond the weekly Saturday pattern, so treat the Roblox event listing and the game’s Discord announcements as the only reliable trigger for when to log in.
Note: Servers cap at seven players, and they fill fast once the countdown goes public. Join 15 to 20 minutes early. Rejoining mid-event burns minutes you cannot get back on the obby leaderboard.
How the Monster Obby race decides who gets a Limited Drill Egg
The obby is not a single completion challenge. It is a repeat-lap race, and the scoreboard counts wins, not finishing position on one run. The on-screen instructions spell it out plainly: race the obby, get wins by passing stages, repeat as many times as you can, and top players win prizes. More wins mean better prizes.
If your jumps feel impossible, rejoin the server
There is one failure case worth knowing before you commit an hour to this. A speed nerf can stick to your character when the obby loads, which shortens your jumps enough that certain gaps become uncrossable no matter how you time them. If you are missing jumps that other players in the same lobby are clearing, the fix is to leave and rejoin the server. Your character loads back in without the nerf and the course becomes completable again.
Rejoin early if it happens. Every minute spent bouncing off the same ledge is a lap someone else is banking.
Hatching the Rainbow Drilla and confirming it worked
The Limited Drill Egg drops straight into your possession at the end of the event, so make sure you have room before the results screen. Clear pen space beforehand by selling or fusing low-income pets, because a full base is a real way to lose a reward you already earned.
Hatch the egg and the Rainbow Drilla appears as a Cosmic pet producing 137M/s. To verify it registered permanently rather than just appearing in the hatch animation, open the Pet Index and check that the Rainbow Drilla entry is filled in rather than showing as a locked silhouette.
For context on where the Rainbow Drilla sits, these are the pets that came out of the same Admin Abuse window:
| Pet | Rarity | Income |
|---|---|---|
| Rainbow Drilla | Cosmic | 137M/s |
| Cosmic Mantaris | Cosmic | 74M/s |
| Monstrous T-Rex | Secret | 150M/s |
| Secret Mutant Shark | Secret | 401M/s |
| Bladehide | Mythic | 1.6M/s |
Note: Rainbow Drilla is a pet name, not a mutation. The separate Rainbow mutation is a 2.5x income multiplier that can roll on any hatch and is also handed out during Admin Abuse. A Rainbow-mutated Rainbow Drilla is possible, and the two are tracked independently.
Other rewards running in the same Admin Abuse session
If you miss the obby cut, the session still has two other reward tracks running in parallel, and both are worth knowing so you are not standing idle between events.
Feeding The Hungry Monster for a Monster Chest
Infested parasite eggs spawn from the Snow biome onward and are marked by a purple glow. Steal one, carry it back to the safe zone, and feed it to The Hungry Monster NPC. Each egg fills the belly bar by 20 percent, so five eggs push it to 100 percent, at which point the monster produces a Monster Chest.
| Monster Chest reward | Chance |
|---|---|
| 1.25X Egg Growth | 43.5% |
| 1.25X Speed | 30% |
| 2X Treadmill Speed | 20% |
| Flyswatter | 5% |
| Monstrous Egg | 1.5% |
Capture the Egg for the Monstrous T-Rex Egg
At night, a giant Monstrous T-Rex Egg drops onto the map. Stealing it starts a timer on the leaderboard, and the player with the highest cumulative hold time when daytime returns keeps the egg. Other players can take it off you, so the winning play is constant movement between biomes rather than parking in one spot.
Everything in an Admin Abuse session is decided in the first few minutes of each event, and the Rainbow Drilla is the tightest bottleneck of the lot because only three players walk away with the egg that produces it. Load in early, keep pen space free, and treat the obby as an endurance grind rather than a race you win once.
