Be like your idle sprite and be proud of your confidence, Popplio. It made me like you. Also, its a tropical region meaning lots of water. You are a necessity!
Brionne always acts cheery and positive. Even when it’s feeling sad, this Pokémon doesn’t allow its sorrow to show. It’s said that Brionne will only reveal a sad expression to a Pokémon or Trainer to whom it has opened its heart completely.
