What Are Hatchmon

Hatchmon are combat pets that hatch from the colorful eggs you pick up in the dungeon. They float along behind you out of combat, then automatically seek out and attack enemies the moment a fight starts — even if you stand still, your Hatchmon are still dealing damage. On top of that, certain weapons and Artifacts scale directly off the number of Hatchmon and eggs you carry, so pets feed into equipment builds as their own subsystem.

• No carry limit. You can hold unlimited eggs and Hatchmon. If the swarm gets distracting, the Settings menu lets you cap how many render on screen without removing any from your run.
• They get knocked out, not killed. A hit from an enemy drops a Hatchmon unconscious. Walk over it to wake it up, or grab a relic like Tenacious Sapling that revives downed Hatchmon automatically after a short delay.
• Elise's Kiddy is the exception. Her signature Hatchmon follows her permanently and never participates in fusion — covered in detail below.
• Veewo has never published a complete Hatchmon roster, so specific names and evolution counts below reflect hands-on testing from the Early Access build onward.

Where Eggs Come From

Source	Notes	Efficiency
Smashing crates, vases, and other breakables	The single most common source; nearly every room has something to break	Primary source
Room-clear rewards	Shares the same behavior that advances hatching, so it does double duty	Reliable source
Chests of any rarity	Quality of the chest doesn't matter	Incidental income
Temple of Shopping	Buy eggs with Gold	Fallback when Gold is flush
Temple of Agapeism	15 Gold per egg; excess eggs can be sold back for Gold	Core of the Agapeism route

Veewo has not published drop rates for any of these sources. One rule matters more than the drop table: an egg's main color determines which Hatchmon it will hatch into, and the pattern on the shell (dots, stripes, and so on) is cosmetic — an egg with pink dots and a pink-striped egg both hatch a Pinky. Once picked up, the game assigns you a random egg belonging to one of the five base types.

Hatching and Dealing With Failed Hatches

• Hatching progress comes primarily from clearing combat rooms, averaging one successful hatch every three to four rooms.
• Hatches can fail. An egg may simply crack into nothing — that is normal attrition built into the system.
• A successful hatch always pops a notification telling you which Hatchmon you got, so silence means the egg failed.
• Artifacts like Dinosaur Skull speed up hatching and let other actions — explosions, for example — also build hatching progress.

When eggs keep failing, you have three止损 options, in order of impact:

1. The central machine in the Temple of Agapeism hatches multiple Hatchmon instantly, skipping the failure roll entirely. This is the core tool for mass-producing pets.
2. The Agapeism node in the Evolve Skill Tree guarantees successful hatches, so normal hatching stops producing empty eggs once unlocked.
3. Shorten the egg cycle. The faster you cycle eggs, the thinner the failure tax gets — prioritize haste Artifacts when pets are the plan.

Pick the route that matches your run

If this run is about unlocking Elise or forcing a specific fusion, commit to the Agapeism path for the guarantee and instant hatching. If pets are just incidental value, clear rooms normally and accept the failure rate.

The Five Base Types and Evolution Counts

There are five base (mini) Hatchmon, and they do not evolve the same number of times:

Base Hatchmon	Egg color	Evolution stages
Pinky	Pink	8
Limey	Lime green	7
Tealy	Teal	7
Purply	Purple	6
Ivory	Ivory white	4

The spread directly shapes fusion planning: Pinky has the largest combination space (8 possible evolutions), Ivory the smallest (4). A lone mini Hatchmon contributes modest damage — its real value is completing a fusion combination and triggering weapon/Artifact bonuses that count your pets. Veewo has not published a full list of evolution-stage and Super Hatchmon names; confirmed examples include Grabie, obtained by taking a loan from the Temple of Shopping (a Consumerism route tie-in). Treat the in-game index as the source of truth for the complete roster.

Super Hatchmon Fusion

• Collecting a specific combination of four mini Hatchmon (for example, 3 Pinky + 1 Limey) triggers an instant, automatic evolution into the matching Super Hatchmon. You cannot opt to hold the fusion.
• The result is strictly determined by the combination. Duplicate minis that don't complete a combination don't disappear — they keep following you until a viable set comes together.
• Super Hatchmon hit harder and carry unique abilities. A few are actually less aggressive than their mini counterparts because of what their ability does.
• A small number of Super Hatchmon have alternate unlock paths: a specific weapon or event. The Grabie-from-a-loan example above is the canonical case.

This "four matching minis" rule matches how Veewo's Creative Director described the system in a GamingBolt interview. Disregard any older write-ups claiming minis merge pairwise — that does not match in-game behavior.

Plan fusion order around your index

The in-game index records Super Hatchmon in the order obtained, and completed combinations permanently consume their minis. If you're chasing a specific Super Hatchmon, use the Color Changing Machine to assemble every mini except the colors needed for lower-priority combinations first, so you don't accidentally trip an unwanted auto-fusion on the way.

Color Changing Machine, Step by Step

The Color Changing Machine is your only active lever over fusion direction — it changes one mini Hatchmon's color in exchange for Gold. Use it deliberately:

1. Decide the target Super Hatchmon for this run. Check the in-game index for combinations you've already unlocked.
2. Audit your current minis. Count the colors you're holding and work out exactly which colors and how many of each you're missing.
3. Convert excess colors one at a time. After each change, stop and check — fusions trigger instantly, and converting too many at once can complete an unwanted combination before you react.
4. When Gold is tight, protect Ivory and Purply. Their smaller combination spaces mean they're the most likely to be swept into a fusion you didn't plan.

The machine only works on mini Hatchmon. Fused Super Hatchmon and Elise's Kiddy are not eligible.

Agapeism: The Hatch Guarantee and Egg Economy

Agapeism is the Faith path bound to Hatchmon, and it turns the entire pet system from a gamble into an assembly line:

1. Unlock the Agapeism perk in the Evolve Skill Tree — finish the first page of nodes, then take Agapeism on the second page. This opens the Temple of Agapeism and grants the hatch-success guarantee in the same node.
2. Earn Agapeism faith by obtaining or hatching eggs. Once the meter is full, enter the Temple of Agapeism through the Pillar of Faith or the teleporter on each floor — see the Faith system page for the full loop.
3. While the faith is active, the Agapeism Proxy spawns randomly in rooms and drops one egg every time it's hit. Prioritize smacking it the moment you enter a room — it's a free egg faucet.
4. Inside the temple you can buy eggs at 15 Gold each, sell surplus eggs back for Gold, and use the central machine to hatch several Hatchmon instantly. Supply, cash-out, and instant hatching all live in one room.
5. The temple disappears when you leave, but you can re-enter on the next floor by picking Agapeism at the Pillar of Faith again.

The fastest Elise unlock

Temple of Agapeism guarantees egg supply and instant hatching, which makes it the quickest path to the "hatch 8 Hatchmon" requirement for unlocking Elise. Stack Agapeism faith, enter the temple, and batch-hatch.

Synergy With Elise and Fate Cards

• Unlock condition: hatch 8 Hatchmon total across any number of runs. It's cumulative, and it's the most worthwhile early character unlock in the game.
• Elise's Agent Item, Plush Gloves, grants her a signature Hatchmon called Kiddy. Kiddy follows her permanently, cannot be fused, and — the standout trait — revives nearby unconscious Hatchmon (as long as they're still revivable). It's effectively a combat medic for your pet squad, which pays off most in dense bullet patterns and boss phases.
• Elise's starting weapon, Warming, fires a random-effect homing bullet every 5 shots, and those shots grow stronger the more Hatchmon you have. That scaling is a concrete reason to keep collecting pets even after Elise is unlocked.
• The Fate Card "Adorable Companion" starts every run with 2 Hatchmon, erasing the early-game egg drought. Stacked with the Agapeism guarantee, it's the speedrun combo for the Elise unlock: open with the card, bank the faith node, and the eight hatches come together within a handful of runs.

Route	Key node	Problem it solves
Agapeism Faith	Skill-tree perk + Temple of Agapeism	Failed hatches, egg supply, instant hatching
Fate Card: Adorable Companion	2 Hatchmon at run start	Early-game drought, Elise hatch counter
Elise herself	Unlock at 8 cumulative hatches	Kiddy sustain + Warming scaling
