Overview
Pearl Oyster is a common regular pet: Turns grit into value — swallowed balls still pay.
It comes from the World 4 · Maelstrom claw machine and carries 3 abilities unlocked one per star.
Abilities
This pet has 3 abilities and unlocks them one per star: the first is live from the day you get it, the second needs 2★, the third 3★ (see fusion below).
| ★ | Ability | Lv 1 | Lv 25 | Lv 50 | Lv 75 | Lv 100 | Charm |
|---|---|---|---|---|---|---|---|
| 1★ | Grit Toll includes the common ×1.00 rarity multiplier | +0.00% | +6.1% | +12% | +19% | +25% | CHARM |
| 2★ | Nacre Layers | 3 | 3 | 3 | 3 | 3 | — |
| 3★ | Seed Pearl | 0.00% | 1.9% | 4.0% | 6.0% | 8.0% | CHARM |
- Grit Toll — Every ball the whirlpool swallows still pays a FULL Grey landing in coins — plus this much on top.
- Nacre Layers — Every 5th swallowed ball pays its toll THREE times over.
- Seed Pearl — A swallowed ball has this chance to hand a ball straight back to your reserve.
Stars and fusion
Fuse 3 copies at the same star into one at the next — guaranteed, at the Fusion forge. The XP invested in all three copies is pooled into the result.
| Fuse | Needs | Essence |
|---|---|---|
| 1★ → 2★ | 3 × 1★ Pearl Oyster |  500 |
| 2★ → 3★ | 3 × 2★ Pearl Oyster | 1,500 |
Each star switches on the next ability in the table above.
Bring a 3★ copy to the Ball Grove to try for amped (purple) stars: each amped star adds +5% to that star's ability (1★ 1 in 10, 2★ 1 in 25, 3★ 1 in 50 on Hard; 1 in 30 / 1 in 75 / 1 in 150 on Regular).
A 3★ copy can become shiny by fusing an owned shiny Pearl Oyster into it for 10,000 — see Shiny pets.
Levelling
Gold balls needed per level for a common pet (level-cost multiplier ×0.4):

10 on top. Untradable (free-pull) copies yield nothing. See Pet Salvage.
