The current game description puts boss fights first: fight Boss Mosquitoes for mosquito eggs. Every documented cash-route egg follows the same path. Defeated mosquitoes were not shown dropping weapons.
One cycle
- Sit until your health is above what the target can drain. First-area bosses are lenient. The Housewife was judged to need about 500 health, probably a little more.
- Walk up to a large mosquito standing in the field. There is no summon and no arena.
- Hit until the bar at the top of the screen is empty.
- Pick up a larva. On a server of up to 7 players you are racing whoever is nearest. Other players' kills stay lootable.
- Place it on the plot. Position was judged not to matter.
- Wait, open the lid, and place the mosquito.
- Feed to 100%. See feeding.
- Step on the green circle.
- Fight the same boss again. Sessions go straight from one kill to the next. One re-fight immediately dropped a fresh, larger larva.
How to tell drops apart
The ground object is a wriggling larva. Players say larva and egg for the same pickup. There is no filmed official label on the drop itself.
- Rarity callouts. First-area drops are all common. Later loot is called a rare egg, and an end-of-fight line reads "Epic egg, mythical, legendary."
- Size. A bigger larva takes longer to be ready.
- Color. A purple larva hatched into an uncommon Venomous mosquito. Color alone is not a stat chart: the owner of a Blue mosquito said he knew of no advantage to the color.
Hatch times that were watched
| Egg | Time observed |
|---|---|
| First common | About 7 seconds |
| A larger early egg | About 12 seconds |
| A mid-tier egg | About 2 minutes |
| A mythical | About 7 minutes |
| A late-game egg | Up to about 4 hours |
Robux can skip a timer. The skip price was not shown. No drop percentages are documented. Re-fighting the same boss produced commons and rares between the good pulls, so plan on volume.
A transcript mentions "a 5 minute cool down" while collecting eggs and never shows what it applies to. Do not treat immediate re-fights as proof that every boss has no timer, and do not treat that one phrase as a global respawn rule.
Sitting restores health. It does not create eggs. Stronger bosses can drop several eggs in one kill. When the plot is full, expand it; one note also says weaker mosquitoes can be benched in a dungeon, but that control was not shown on screen. Named hatches are on the mosquito list.
