We got to see snow and that was nice. My favorite scene was Chikorita fighting Charizard and managing to trip his feet + I liked Meowth's snowball machine.
I loathed this episode because I never liked Chikorita much. But at least Chikorita got some character development unlike Cyndaquil and Totodile did when they first got caught.
It was a nice callback when Satoshi remembered his encounter with Nanako when he saw the wild Chikoriita here. This Chikoriita was quite feisty and stubborn, though. Satoshi kind of overdid it when he used his Lizardon against Chikoriita, but I liked when the Rocket-dan tried to get Chikoriita to join them.
