I'll tell you this: He's a really mean pirate, even in Dora the Explorer.

The one who appeared in Dora the Explorer, are a completely different Captain Hook, and yes he's mean, in the Peter Pan movies he's much worse than in Jake and The Neverland Pirates as i mentioned earlier, cause on Disney Jr he's just angry, grumpy, thief

Yep, that is Captain Hook all right.

It feels so nice at the island where's Jake, Izzy, Cubby, and Skully are lives in

Do you remember the part where those 4 count the dubloons they've found during their adventures (because that's the part that I remember the most)?

I kninda remember, they gathers many different quantities of these dubloons in each day

That's right: different amounts of dubloons every day (like Super Why's Super Letters).

Yeah, and in one episode kinda interesting was when there was only three letters, and in the other one so many was, and Whyatt were giving an interesting reactions about them

Yep, I remember that.

Even in Let's go Luna some alike moments being different, when the circus was in india, Andy and Carmen has bickered, and then Leo were kinda upset about it, and when he met Luna alone, he sang a whole song by his own, and in the christmas the whole circus were singing about her
