See the documented Grow A Colony Snake routes: the 599 Robux permanent Pass and archived 2.5% per completed Snake Raid model, rechecked for live Update 6.
The current API lists Snake (Perm) for 599 Robux and says it grants Snake. The free route comes from an archived Update 5.5 statement of 2.5% per completed Snake Raid. Update 5.9 recorded three Raid waves. Update 6 does not itemize a Raid change; recheck the live structure before using the historical guide. The rate and per-wave rolls are not reconfirmed.

Historical outcome: the Update 5.5 description gave each full completed Snake Raid a 2.5% chance.
Current boundary: Update 6 does not reconfirm the entrance, rate, cooldown, party rule, pity system, or reward timing.
Current price: 599 Robux on September 9, 2026.
Listing effect: the official description says the Pass grants Snake.
Tradeoff: confirm the live checkout; the API does not publish Snake combat stats or a value ranking.
A missing purchased benefit is a different issue from an unsuccessful Raid drop. If you bought Snake (Perm) but cannot find its benefit, follow Pass purchase help. Do not use the historical Raid probability calculator to diagnose a paid purchase.
Only the completion and chance are official; current in-game prompts must supply the missing access steps.
Open place 103154273080028 by sebcaddy1. A matching title from another colony game does not share this Raid or reward model.
Confirm that the current Update 6 game presents a Snake Raid, then follow only the entrance and prompt shown live. No permanent entrance, trigger, team size, or cooldown is published.
If the live Raid still has the recorded three waves, follow all three. Do not record a modeled Snake attempt after entry or one completed wave.
Wait for a full completion or visible result. The archived chance was tied to a completed Raid, so failed runs and partial waves do not belong in the model.
Treat 2.5% as the historical Update 5.5 input. Update 6 does not restate the rate or confirm a separate reward check for each wave.
The table models independent attempts at the archived 2.5% rate.
| Completed raids | At least one Snake | No Snake yet |
|---|---|---|
| 1 | 2.5% | 97.5% |
| 5 | 11.9% | 88.1% |
| 10 | 22.4% | 77.6% |
| 20 | 39.7% | 60.3% |
| 28 | 50.8% | 49.2% |
| 40 | 63.7% | 36.3% |
| 50 | 71.8% | 28.2% |
| 60 | 78.1% | 21.9% |
| 80 | 86.8% | 13.2% |
| 100 | 92.0% | 8.0% |
Update 6 does not restate the historical 2.5% Snake rate or publish a relationship between Beetle and Snake. Beetle has a separate 499 Robux Pass; no public free route is confirmed.
How to Get BeetleEntry, damage dealt, one completed wave, and a failed run are not described as completed Raid attempts.
Update 5.9 changes the Raid structure but does not say Snake is checked after each wave.
At 40 independent completions, the modeled no-drop chance is still about 36.3%.
Under the stated independent-attempt model, the next completion remains a 2.5% chance.
Best when you prefer the free route, enjoy the raid itself, and accept an uncertain number of completions.
Best when certainty matters more than the current 599 Robux cost and you expect to use Snake enough to justify it.
Best when your decision depends on Snake stats, raid time, or cooldown—none of which is confirmed here.
Check any full completed Raid count without multiplying waves.
Prepare, follow all three waves, and identify a full completion.

The current official API lists a 599 Robux Snake (Perm) Pass that grants Snake. An archived Update 5.5 announcement also documented a 2.5% chance per completed Snake Raid; confirm that free route in the live Update 6 game.
No current source confirms that. The archived wording was per completed Raid, not per wave.
The current public description does not restate the rate. Keep 2.5% labelled as the archived Update 5.5 model until it is reconfirmed.
Forty raids is not a guarantee. Under an independent 2.5% model, there is still about a 36.3% chance of no Snake after 40 completions.
No pity or guaranteed count was stated in the archived Update 5.5 description or the current Update 6 description.
The current official API listing is named Snake (Perm), costs 599 Robux, and says it grants Snake inside Grow A Colony. It does not publish Snake stats.
