I think there should be an Xmas Hippopotas. This came to me while I was trying to train some Pokemon.
I want a Hippopotas for Christmas
Only a Hippopotas will do
Don't want Riolu
Or an Eevee or a Flaaffy
I need a Hippopotas to really make me happy
I want a Hippopotas for Christmas
I don't think pro's staff would mind, do you?
Design them for the season, create a new code
Sure they're higher tier but don't make this hard mode
I just want them in or Christmas will be blue
Can't you see us logging in on Christmas morning
imagine our joy and great surprise
When a Pokemon does materialize
And our encounter at the finish
Reveals a hippo hero, nature impish
I want a Hippopotas for Christmas
Only a Hippopotas will do
No dragoniers, no senereteses
I only like Hippopotases
Unlike my numel, I think they'd like me too
They're not cute to many, they ain't a region starter, they don't even got a mega form
But only fools would underestimate them when they bring out their sandstorm
I've got lots of space for them and their friends in my poke center boxes
So after every battle, I'd take them to goldenrod for messages
Can't you see us logging in on Christmas morning
imagine our joy and great surprise
When a Pokemon does materialize
And our encounter at the finish
Reveals an epic hippo, nature impish
I want a Hippopotas for Christmas
Only a Hippopotas will do
No ursarings or gardevoireses
I only like Hippopotases
And Hippopotases like me too!
