Froakie

You pick the water type Froakie. Shauna takes Fennekin and serena takes Chespin. You remember what your mom said earlier and tell everyone you want tpgo say goodbye to her.

"Before you go, we need to have our first Pokemon battle!" says Shauna. You both send out your starter Pokemon. You have the type advantage, so you easily win. "Oh, you won! So, what's my punishment going to be?"
