Can Contagion spread be stopped mid-session?

Removing Plague Rat from garden stops new spread immediately. Existing toxic tags on already-affected crops persist until harvest or cleanse.

Plague Rat or Spore Frog for toxic mutations?

Spore Frog Fungal Leap controlled toxic boost in jungle humidity at rare tier B. Plague Rat Contagion uncontrollable toxic spread at uncommon tier D. Controlled builds pick Spore Frog; deliberate spread experiments pick Plague Rat with quarantine.

Playstyle

Plague Rat is high-risk toxic spreader. Contagion spreads toxic mutation to adjacent crops uncontrollably — unlike Spore Frog controlled toxic boost. Uncommon tier D at 0.6 kg — tier D reflects spread risk not ability weakness. Isolate Plague Rat on quarantine wing separated from main harvest rows by empty path tiles.

Weight & trading

0.6 kg hatch caps near 6.0 at age 100 — light uncommon tier D. Plague Rat trades cheaply — niche toxic spread builds only. Ladybug Pest Control on main plot prevents disease from toxic overrun crossing quarantine boundaries partially.

Contagion spreads toxic mutation to adjacent crops passively without player control. Spread is continuous while Plague Rat deployed — removal stops spread but existing toxic tags persist on affected crops. Newt Regenerate toxic boost on healed crops creates toxic-heal loop if spread is contained.

Quarantine wing protocol

Build Plague Rat wing minimum two empty tiles from main harvest cluster — Contagion ignores intended targets and spreads to all adjacent crops. One tile gap insufficient per community spread testing.

Toxic mutation on premium crops can boost or destroy sell value depending on crop toxic eligibility — verify crop compatibility before enabling Contagion spread.

Controlled vs uncontrollable toxic

Spore Frog Fungal Leap controlled toxic boost in jungle humidity. Shroomie Spore Cloud directed overgrown-toxic on mushroom plots. Plague Rat Contagion uncontrollable spread — highest risk toxic source in roster.

Plague Rat tier D uncommon — retire after Shroomie or Spore Frog cover toxic needs unless running deliberate toxic spread challenge builds.
