I suppose you are correct, both in your answer and assumptions. Trust me though that the next riddle will not be so easy.
Litten's final evolution is a quite rounded tiger. And by that, I mean it looks VERY fat, and also mostly black in coloration with a bit of red. Its tail by this point is now a long wick, which lights up during attacks. Reminded me of Purugly in a way, although even fatter somehow.
This next one is information for the Water starter, Popplio's, final evolution. And this time, I'm making certain it will not be easy to solver. So then, RIDDLE ME THIS:
I rise and fall throughout the month.
Some curse me, others love me.
And when the sun is hottest, I am a sign of joy to some.
What am I?
