That's what Chesnaught is. He's a ripening chestnut that splits open in the final evolution.
And, like all chestnuts, he's best roasted.
Not a fan. Chespin was okay, but both the evolutions fell apart.
Fennekin was cute, Braixen had a quite solid design, and Delphox was conceptually awesome, but so BORING in execution.

That? Awesome.

That? Sooooo boring. No life, no style, no flair. It just stands there.
Froakie is the only one who I feel is great through all its evolutions, and all its designs. It manages to have a style and personality, even in just its minor animations and stances.
