Unofficial wiki for [🎃] MOUNT RNG on Roblox: working and expired codes, Luck stacking, islands, Essence, and documented mounts for version 1.54.
LESSON5 is widely listed as a Johnny Joestar mount. Older descriptions printed this code during the period around Update 41 and again in Update 50 notes. The version 1.54 page does not print it.

Redeem LESSON5.
Showcase and a ride that passes time while you travel.
MOUNT RNG is a Roblox incremental simulator by TaleSun Studios. You roll for more than 700 mounts, sell duplicates for Essence, unlock islands, and fight beasts. Version 1.54, Update 54, is the Halloween update described on the official page.
Like the game, join the TaleSun Studios group, and turn on notifications for +20 Luck. Each friend in your 12-player server adds +5 Luck, and those bonuses stack. Free ground potions add +50 Luck for one minute. Buy Ultra Luck only after that free stack is on.
Try CORTISOL, FORTNIGHT, LESSON5, SIGH, and 2YEARS first. Mid-October 2026 lists repeat those more often than the rest. The other active rows are still printed by at least one October list and marked expired by another, so enter each one once and stop if it fails. The live version 1.54 description does not print code strings.
The Roblox catalog for this experience lists seven badges: Welcome to Mount RNG, Auntum Fields, Paradise Island, Frozen Reach, Celestial Peak, The Magma Lair, and Against the Test of Time for obtaining Azatoth on the secret island.
