Why Hygiene Matters

Official descriptions emphasize lab health and mischievous Fulus. Hygiene is a production multiplier: clean labs keep machines running smoothly, shorten downtime, and prevent cascading slowdowns during long synthesis runs.

Positive Signals

Machines complete cycles without delays.
Fulus recover at expected speeds.
Orders flow without sudden stalls.

Warning Signs

Repeated delays between machine cycles.
More frequent accidents or interruptions.
Recovery taking longer than usual.

Daily Hygiene Routine

Start of Session

Walk the lab and clear bottlenecks.
Check for hygiene alerts or slow zones.
Move exhausted Fulus into habitats.

Mid-Session

Insert a cleanup window between batches.
Fix any stalled machines before queueing more.
Track which areas get messy fastest.

End of Session

Leave the lab clean for the next login.
Log any recurring hygiene issues by version.
Queue recovery so Fulus start fresh next session.

Fulu Mood & Mischief Control

Mischievous behavior increases when recovery and care routines are ignored. The safest approach is to keep habitats aligned with element types, rotate tired Fulus out of high traffic zones, and avoid overcrowding during long synthesis runs.

Calming Practices

Rotate battle teams into matching habitats immediately.
Keep 1-2 idle slots in habitats for quick swaps.
Use orbs to preserve your best Fulus before risky tests.

Lab Layout Tips

Keep habitats on the return path from battle stations.
Separate high-traffic machines to reduce congestion.
Leave space for future expansions without crowding routes.

Weekly Hygiene Checklist

Run a cleanup window before long synthesis batches.
Log any machine slowdowns with version details.
Keep recovery habitats aligned with your active elements.
Leave room for movement between habitats and machines.
