Got it yesterday, and it's really good. Keep dieing from the sharks though if I don't have any PP left, lol. I'll have to grind on the snakes 
lol the snakes. "The Sharks' boss" (not to spoil anything, even if you probably already know) is kinda tough, you should have some hamburgers and buy the best equipment at the store first. Also, "the first boss" is kinda tough too, I beat it at level 12, almost 13.

I recommend you to learn PSI Rockin before battling it, it's really helpful.
I'm in Happy-Happy Village right now btw.
