Totodile evolves into Croconaw starting at level 18. Then Croconaw further evolves into Feraligatr starting at level 30. This evolution process has been consistent across multiple Pokémon games including recent ones like Pokémon Scarlet & Violet and Pokémon Legends: Z-A. So for a player, once Totodile reaches level 18, it will evolve automatically into Croconaw, and upon reaching level 30, Croconaw will evolve into Feraligatr.
