CORTISOL, LESSON5, FORTNIGHT, SECRETDEV, URARA, UMAMUSUME, UMAMUSUMEAGAIN and SIGH as new, and Twinfinite (Oct 19, 2026) now splits with Destructoid over five further strings.LESSON5 and CORTISOL, which we promoted to first-party standing last time, rest on tracker-sourced status only: Roblox Den (its own date August 16, 2026) and Beebom (August 1, 2026) list them, while Pocket Tactics (August 12, 2026) carries CORTISOL in neither of its columns. That is a reason to downgrade how they are labelled, not a reason to delete them — no source says either code has expired, and every tracker read on this page predates the description change. Both rows now read as try-with-caution, and every August date below is five weeks stale rather than current. None of this is an in-game check by us.What the Developer Publishes Now
The official Mount RNG experience was re-read through the Roblox API at 07:35 UTC on September 20, 2026. The listing runs under the live title [X2 LUCK🍀] [🐲] MOUNT RNG, its platform update field reads September 19, 2026, and the description advertises Update 53 at version 1.53 on a stated two-week cadence. In that text there is no code, no CODES heading, and no milestone string — nothing for us to point at for any code on this page.
Say precisely what that proves, because it is less than it looks. It proves the strongest argument this page made in August no longer exists. It does not retire anything: a developer deleting a code block from a description is not an expiry notice, Mount RNG has never published expiry dates, and from a deleted paragraph we cannot say in either direction whether a string still redeems. The same absence cuts both ways on the Umamusume rows below, which is why their statuses are left where the trackers put them rather than being moved up on the strength of a deleted paragraph.
What is left is three dated tracker pages, the newest of them five weeks old: Roblox Den (August 16, 2026), Pocket Tactics (August 12, 2026) and Beebom (August 1, 2026). Nothing in this table has first-party support in either direction at this check, and we have not redeemed any of these strings ourselves.
Codes to Check First
| Code | Reward / Signal | Status |
|---|---|---|
| LESSON5 | Johnny Joestar mount per Pocket Tactics and Roblox Den; Beebom says only an exclusive mount. No first-party reward figure is published anywhere, and the description no longer names the code at all | Marked New by Destructoid (Sep 1, 2026), the page our September pass missed. Still tracker-sourced only: Roblox Den (August 16, 2026), Pocket Tactics (August 12, 2026) and Beebom (August 1, 2026) also list it active, and the developer's description prints no codes |
| CORTISOL | A Low Cortisol exclusive mount | Marked New by Destructoid (Sep 1, 2026), the page our September pass missed. Roblox Den (August 16, 2026) and Beebom (August 1, 2026) also list it active, while Pocket Tactics (August 12, 2026) still carries it in neither column |
| FORTNIGHT | Battle Bus mount | Marked New by Destructoid (Sep 1, 2026), the page our September pass missed. All three trackers on our citation line also list it as working — Roblox Den (August 16), Pocket Tactics (August 12), Beebom (August 1) — none re-read since |
| SIGH | The old Floating Cube mount per Pocket Tactics and Beebom; Roblox Den states no reward detail | Marked New by Destructoid (Sep 1, 2026), the page our September pass missed. All three trackers on our citation line also list it as working — Roblox Den (August 16), Pocket Tactics (August 12), Beebom (August 1) — none re-read since |
| SECRETDEV | Exclusive Wyvern DEV Mount per Destructoid; Twinfinite says Wyvern DEV Mount | New at this recheck — marked New by Destructoid (Sep 1, 2026) and listed active by Twinfinite (Oct 19, 2026). No older tracker on our citation line carries it |
| URARA | Haru Urara mount per Destructoid | Reinstated at the October 24, 2026 recheck: Destructoid (Sep 1, 2026) marks it New and Twinfinite (Oct 19, 2026) lists it active. Roblox Den (August 16, 2026) still files it expired; Pocket Tactics (August 12, 2026) and Beebom (August 1, 2026) show it working |
| UMAMUSUME | Exclusive Mount per Destructoid | Reinstated at the October 24, 2026 recheck on the same reading as URARA — Destructoid (Sep 1, 2026) marks it New; Roblox Den (August 16, 2026) still files it expired |
| UMAMUSUMEAGAIN | Exclusive Mount per Destructoid | Reinstated at the October 24, 2026 recheck on the same reading as URARA — Destructoid (Sep 1, 2026) marks it New; Roblox Den (August 16, 2026) still files it expired |
Disputed — Twinfinite Against Destructoid
Five strings sit in opposing columns at this check. Twinfinite (Oct 19, 2026) lists all five as working; Destructoid (Sep 1, 2026) files all five as expired — and for BILLCYPHER20 and BANANAC4T, Destructoid's own page also carries them in its active column, a self-contradiction we record rather than resolve. None of these five was carried on this page before the October 24, 2026 recheck.
| Code | Reward / Signal | Status |
|---|---|---|
| BILLCYPHER20 | Star per Twinfinite; Destructoid prints no reward detail | Twinfinite (Oct 19, 2026) lists it working; Destructoid (Sep 1, 2026) files it expired — unresolved split, and Destructoid also carries it in its own active column |
| BANANAC4T | 12k Essence per Twinfinite; Destructoid prints no reward detail | Twinfinite (Oct 19, 2026) lists it working; Destructoid (Sep 1, 2026) files it expired — unresolved split, and Destructoid also carries it in its own active column |
| BTSBT9 | 12k Essence per Twinfinite | Twinfinite (Oct 19, 2026) lists it working; Destructoid (Sep 1, 2026) files it expired — unresolved split |
| REDBORNE | 12k Essence per Twinfinite | Twinfinite (Oct 19, 2026) lists it working; Destructoid (Sep 1, 2026) files it expired — unresolved split |
| TATABT21 | 12k Essence per Twinfinite | Twinfinite (Oct 19, 2026) lists it working; Destructoid (Sep 1, 2026) files it expired — unresolved split |
Sources checked October 24, 2026: Destructoid (its own stated update: September 1, 2026 — the page our September pass missed, and the basis for the New flags above), Twinfinite (its own stated update: October 19, 2026), the official Mount RNG Roblox experience (last re-read September 20, 2026), Roblox Den (its own stated update: August 16, 2026), Pocket Tactics (its own stated update: August 12, 2026) and Beebom (its own stated update: August 1, 2026). The last three were carried at their own dates and not re-read on this pass. GGGuides labels these as dated signals unless confirmed in-game.
Reported Expired
Rows leave the table above rather than being deleted, so returning readers can see what changed. The Umamusume-family rows and URARA moved back up to the table above at the October 24, 2026 recheck, on Destructoid's New flag; their history now sits on those rows.
| Code | What changed | Status |
|---|---|---|
| DINO, GOOSE | Beebom (August 1) still lists both as working mount codes. Pocket Tactics (August 12) and Roblox Den (August 16) both file them as expired — two dated trackers against an older one. The description no longer carries any code, so there is no first-party position on these either way | Reported expired by the two fresher lists |
| 10KLIKES | Roblox Den (August 16) still shows a row for it, flagged for checking, attaching a 12,000 Essence reward. Pocket Tactics and Beebom both file it as expired. As a milestone check: the live upvote counter read 250,769 at 07:35 UTC on September 20, 2026, against 244,141 at the August 16 reading, so the ten-thousand-like milestone was passed long ago and its reward window has almost certainly closed with it | Reported expired; milestone long since passed |
| LIKES500LOL, SPOOKY13, RICHLIKETHAT, 1MILVISITS | Carried on this page in July. Pocket Tactics (August 12), Beebom (August 1) and Roblox Den (August 16) all place them in their expired tables | Reported expired |
How to Redeem
- Open Mount RNG from the official Roblox experience page.
- Find the Codes, Shop, Rewards, or Settings menu after your character loads.
- Paste one code exactly as shown, including numbers and capitalization.
- If it fails, rejoin a fresh server and check whether the code expired, requires a level, or was already redeemed.
Why a Code May Fail
Common causes include expired milestone rewards, old servers, typo-sensitive capitalization, one-use redemption, region or group requirements, and update delays.
Update Rule
We do not mark a code as active just because another page says it is active. The page records what was checked, when it was checked, and what players should verify next.
