How to unlock Caterpie

To add it to your League, complete its challenge — evolve 3 times during your runs — then weaken and catch it when it appears in your next run.

League challenge1 step
  1. Evolve 3 times during your runs.
    Goal: 3
  2. Catch it in your next run.
    After the challenge is complete, Caterpie appears in a run. Weaken it and catch it — it only joins your League once it is caught.

"In a single run" goals must be met in one run; the others add up across all your runs. League-size goals count the partners you have caught.

These are the four moves listed in Caterpie's League kit. You start a run with the first one; the other three are among the moves level-up cards can offer (partners can also be offered moves from their evolution line and from your League — see level-up cards).
