Related Grass Systems

World Center near the Rot Lab hosts the EXP Candy machine (240 EXP per candy via Robux). Teleport only works to Rot Lab markers—use that when the party faints mid-route. Zone overview: all zones.

Community notes also mention Rot Forest key routes (3 keys, then more toward Goatini Freezini). Treat named sub-areas as Grass-progression beats until later worlds unlock.
