How to unlock Shellder in PokeBonk
Shellder joins your League in two steps. First, finish its League challenge; the counters add up across runs unless a goal says "in a single run":
- Dodge 25 attacks in a single run.
Catching Shellder
Then Shellder can show up as a Wild Encounter in your next runs, 50 to 120 seconds into a zone. It runs away after 150 seconds, so weaken it and throw a Poke Ball before then. The PokeBonk unlock Pokemon guide lists every challenge.
Shellder moves in PokeBonk
Each League Pokemon has a fixed kit of four moves. Move 1 is equipped from the start; moves 2, 3 and 4 are offered as new-move cards at player levels 2, 4 and 7. A run holds three moves until you buy the 4th move slot in the Lab. Hit damage below is the move's base hit at level 1 before your stats, items and type bonus; cooldowns shrink with attack speed.
| Slot | Move | Type | Class | Shape | Unlocks | Base hit | Cooldown |
|---|---|---|---|---|---|---|---|
| 1 | Clamp | Water | Physical | Strike | Start | 19 | 0.81 s |
| 2 | Icicle Spear | Ice | Physical | Burst | Level 2 | 5 | 0.98 s |
| 3 | Ice Spinner | Ice | Physical | Spin | Level 4 | 12 | 0.74 s |
| 4 | Icicle Crash | Ice | Physical | Heavenly Impact | Level 7 | 21 | 1.58 s |
Shellder passive: Skill Link
+20 armor and +1 projectile. Like Cloyster, +1 projectile and +10 more armor.
Clamp matches Shellder's type, so it deals 25% more damage (same-type bonus). Moves can also be learned from its learnset and from other League members of the same type, which the PokeBonk beginner guide explains.
Shellder Ultimate in PokeBonk
Shellder's Ultimate gets stronger as the line evolves: each form has its own version. Press R (Y on a controller) when the bar is full, or turn on Auto Ultimate with the Y key. The PokeBonk Ultimate guide explains how the bar charges.
| Form | Ultimate | Duration | What it does |
|---|---|---|---|
| Shellder | Pearl Shell | 1.8 s | You shut yourself in your shell (30% shield) and when you open it you fire two rings of 20 pearls that freeze. |
| Cloyster | Icicle Rain | 2.8 s | The shell, eighteen icicles falling from the sky on the enemies and a ring of ice spikes around you. |
