The Mystery Egg Box – Support is a Legendary chest in Aniimo that hands you one Perfect Support Aniimo egg at random. Every egg inside is guaranteed to hatch a creature with Perfect potential, so the reward is worth claiming even if you cannot pick which support you get.
Quick answer: Log in on six different days during the Set Out, Pathfinder! event to earn the Mystery Egg Box – Support as the sixth-day login reward.
How to get the Mystery Egg Box – Support
The chest is tied to the Set Out, Pathfinder! login event. Once you reach the sixth day of logins, the Mystery Egg Box – Support is delivered as that day’s reward. The days do not have to be back to back, but they must fall inside the event window.
The event remains available until October 15th, 2026, beginning on September 16th, 2026. Log in on six different days before it ends to claim the box.

| Type | Chest |
| Rarity | Legendary |
| Stack size | 9,999,999 |
| Possible eggs | Perfect Fragrancier Egg, Perfect Dreaple Egg, Perfect Melloblum Egg |
Opening the box gives you exactly one of the three eggs at random, and each hatches an Aniimo with Perfect potential. You cannot choose the outcome, so the value comes from getting a top-tier support regardless of which one drops.
Which egg is the best pull
All three supports are strong, but each one fits a different team. The right pick depends on what your roster already runs.
Fragrancier and Dreaple for Dark teams
Fragrancier is an all-around Dark support. It heals the team, applies buffs to allies, and debuffs enemies, which makes it a staple for any Dark composition.
Dreaple also shines in Dark teams. It applies Nightmare to enemies, lowering their Dark Resistance and leaving them unable to act, which raises the whole team’s damage output.
Melloblum for Thornblade DPS
Melloblum is built around Grass critical hits, which pairs directly with a Thornblade carry. Its ceiling drops sharply if your team lacks Thornblade or another Grass critical DPS, so keep this one for a Grass-focused lineup.
How to open the Mystery Egg Box – Support
You will know it worked when the new Perfect egg appears in your inventory and the box is consumed. From there you can hatch the egg to add its support Aniimo to your roster.
