You had Greninja forever ever since you chose it to be your first starter pokémon. For so long, you two have been a great duo for a year or more. You remembered how your Pokémon used to be a Froakie from the start, then it went to frogadier, then its last evolution. Greninja. The pokémon that you have not expected to become onced it evolved.
Greninja has been very helpful to you and also pretty nice to you. It's like you two are best friends. Which is obviously frue, due to the amount of times you two have hung out almost everywhere you would go.
At this month, is the day when the temperature drops to the time when most pokémons would need to find a warm shelter to hibernate.. Winter.
Yes,outside of your area is snowing a lot! To the point you cannot see the grass anymore from the backyard. Wow the snow is sure letting its flakes fall from the sky to the ground. Seems like a great thing for Ice type pokémons to go outside and have fun.
Speaking of Pokémon.. Your Greninja is currently wrapped in a blanket, trying to warm itself up from the cold, after going outside and accidentally fell on top of the snow. Greninja is currently sitting in front of a fireplace as it shivered from how cold the snow has effected its skin.
"Gre.. Ninjaa..." Greninja muttered in a shaky way, and sneezed from the cold getting to it.
