Lookup and field meanings

In the 2026.10.8 PC build, a normal egg hatches after one hatch-progress trigger from an eligible item or the Temple of Cuteness; it does not hatch just from time or clearing a room. A normal attempt succeeds about two times in three over time, and two failures cannot occur consecutively. A hit knocks a Hatchmon out rather than killing it; touch it to wake it. CapyDB lists 49 Hatchmon, including 17 baby forms and 32 Super Hatchmon, with recipes and effects.

How eggs hatch

  1. Pick up an egg; it follows the Agent.
  2. Get an item or effect that adds hatch progress and meet its trigger. Examples include killing enemies, taking damage, using a Crystal-cost Curio, opening a clown box or destroying obstacles.
  3. One progress trigger fills a normal egg. A normal hatch succeeds about two times in three over time; the extracted data says two failures cannot occur in a row.
  4. A success produces one of five basic Hatchmon at random: Purply, Tealy, Ivory, Pinky or Limey. A failed attempt consumes the egg and drops coins.

The Temple of Cuteness can provide a free hatch wheel; the Lightbulb Curio can spend Crystals to hatch an egg immediately. These details are for the named PC build.

Baby Hatchmon and Super Hatchmon

CapyDB lists 49 Hatchmon: 17 baby forms and 32 Super Hatchmon. Four baby Hatchmon combine according to a specific recipe. Boxie uses three Limey and one Purply; Chirpie uses two Limey and two Purply. See the full Hatchmon catalogue for each companion’s effect, source, damage and recipe.

Hatchmon are knocked out, not killed

The build-specific guide says a hit knocks a Hatchmon out; touching it wakes it at full health. Some companions, including Kiddy and Chirpie, can wake others automatically. The reference is unofficial and may not reflect later patches or console differences. For the related Agent tasks, see Agents and unlock records.
