Disco is the party-lights event mutation at 45×—festival flash tied to Disco Bee and celebration weather, stackable in the env bracket, and easy to confuse with Rainbow’s growth-slot prismatic look.
mutations.ts: party lights from Disco Bee and festival events. weather.ts Disco Lights lists Disco, Rainbow, and Shiny. That weather name replaces vague “party weather” labels. No festival weekend calendars or Disco Bee proc percentages live in the data files.
Weather tie-in: Disco Lights · Full mutations guide
Disco is event-category, stackable, environmental. Formula: growth × [1 + (sum env − count)]. Solo Disco → 45. Disco + Pollinated (6×) → 1 + (51 − 2) = 50. If Rainbow takes growth while Disco is env, you multiply growth by the bracket—you do not multiply Disco × Rainbow as two env tags. Disco has no CONFLICT_PAIRS rows. Glitched is separately non-stackable; do not invent a Disco override rule.

Disco applies a 45× multiplier in the event bracket. The table below shows the value it adds to a reference crop (base 50) across common harvest weights, so you can gauge how much this tag is worth before chasing it.
| Weight | Base crop value | With Disco (45×) | Value added |
|---|---|---|---|
| 1 kg | 50 | 2.25K | +2.2K |
| 2 kg | 200 | 9K | +8.8K |
| 5 kg | 1.25K | 56.3K | +55K |
| 10 kg | 5K | 225K | +22K |
Disco Lights weather can award Disco, Rainbow, and Shiny. Rainbow and Shiny are growth-category; only one growth mutation applies. Disco remains environmental at 45× when its icon is present. A harvest can therefore show Disco plus Rainbow without violating growth exclusivity—different slots.
Shiny at 5× loses to Rainbow at 50× if both somehow compete for growth; the calculator keeps the max growth multiplier. Disco still adds (45 − 1) into the env sum when counted.
Pollinated is the bee/butterfly pet environmental tag. Disco Bee is a pet path mentioned for Disco itself; Pollinated is a different id. When both Disco and Pollinated show, sum 45 + 6, subtract 2, then apply growth.
Enchanted is a spirit-pet environmental neighbor often linked thematically with celebration farms. It does not require Disco Lights. Use related links for reading paths; compute only the icons on the crop.
