๐ The goal
Seed at least **five alien-hybrid children** across town while your alien is **never exposed**.
๐ Packs required

๐ก Strategy tips
- Abductions (more likely while in the Scientist career and stargazing at night) can result in your *male* alien returning pregnant โ a discreet way to produce hybrids without a partner.
- Spread hybrids across households so no single family looks suspicious.
- Keep the disguise up religiously; a single un-disguised public moment can blow the whole run.
