So I know some of you guys might be dissapointed about Goodra (I'm not, it's a pile of draconic sludge, what else do you need?) but here's something to think about:
What does Goodra evolve from? Sliggoo.
And what is Sliggoo? A snail-dragon.
And what does Sliggoo have on it's back, since it's a snail dragon? A shell.
And what do I hope it's gonna do with that shell?
SMASH IT.
A Shell Smash-ing goo dragon. Take a second to regain control of your senses, and then read it again because it's a fricking Shell Smash-ing goo dragon.
In all seriousness though, I wouldn't be surprised if Goodra did end up with Shell Smash, thanks to its prevo and all. One can hope...
