When do these Pokemon evolve in "Pokémon: Adventures in the Orange Islands"?

Question

Ash's Krabby → Kingler
Ash's Pidgeotto → Pidgeot

Answer 1

Both of those Pokemon evolve before the Orange Islands episodes.

Krabby evolves into Kingler in the episode Round One - Begin! (episode 75), the first episode of the Kanto League.

Pidgeotto evolves into Pidgeot in the episode Pallet Party Panic! (episode 81) when defending its friends from Fearow.

Both episodes were part of the first season, before Adventures in the Orange Islands
