What is how to evolve pawmo?

To evolve Pawmo into Pawmot in Pokémon Scarlet and Violet, you need to follow these steps:

1. Level Up Pawmo: First, raise Pawmo to at least level 18. There isn't a specific level requirement to trigger the evolution, but it must be able to level up.
2. Use Let's Go Feature: This is the key! You need to use the "Let's Go" feature. Make sure Pawmo is following you outside of its Poké Ball.
3. Walk 1000 Steps: With Pawmo in the "Let's Go" mode, walk 1000 steps in the overworld. Battles do not count towards this step count. The game doesn't give you an exact counter, so you'll need to estimate.
4. Level Up After Walking: After walking the 1000 steps, the next time Pawmo levels up (through battle, Rare Candy, Exp. Candy etc.) it will evolve into Pawmot.

In summary, level up Pawmo, walk 1000 steps in "Let's Go" mode and then level it up again to trigger the evolution.
