What are Secret pets?
Secrets are hidden from egg preview screens yet can hatch from any egg in the game — even the cheapest Forest Egg in World 1. That universal pool makes World 1 the economic capital of Secret farming.
Odds range from roughly 1-in-250,000 for Rubix up to 1-in-25,000,000 for Reaper X. Secret Agent enchants and SA Huge pets multiply your effective odds — details in the secret hunting guide.
All known Secret pets
Sharktide commands the highest routine trade value. Plank sits at one-in-a-million fame. Captain Bubbles and Rubix form the entry ladder for new Secret owners. Spider Queen and Reaper X occupy the ultra-rare ceiling.
World 1 AFK farming method
Accumulate Energy, mark every visible rarity with X on the Forest Egg, enable Auto Hatch (and Triple Hatch if available), then leave the session running. Only Secrets appear in inventory because listed rarities auto-delete.
Pair this with Energetic farming teams first — you need millions of Energy per session. The full secret guide covers SA team building and Huge pet requirements.
