We fond Rico, Marlene and Private in fanpop but... what about Kowalski?

There have been two Kowalskis here from what I remember. There was also a King Julien and a Skipper. I don't think they're around anymore, though.
This Kowalski is still around it seems: link

There's been multiple Skipper's here. I don't think any of them have been active lately. I've never seen a Julien, but there must have been one at some point. Kowalski is still around quite often. His name is Lt_Kowalski. I can't believe you haven't noticed him before, he's quite..."noticeable." XD

You're kidding me, right? Lt_Kowalski, you don't ever see him around? He's been around as long as I have.

There were also maybe 5 Skippers, but they're all gone right now, and we used to have a Julien, but he hasn't been around in forever.

Lt. Kowalski is here sometimes! Skipper...Well, the official one doesn't visit. Indeed, we could use a Skipper. King Julien? Used to, then "bai bai!"

There are blowholes also AKA me!

Yes, thank you for missing me! I did not care for the, eh, computery stuff, but Kowalski showed me, and I am to be changing my mind. Looky! I am connected!

I'm here, soldiers.

There's definitely a Kowalski! It seems we now have a Julien and a Skipper too. Yay! Is the Private we have still active? I haven't seen him, I don't think.

por the time it takes you to read this, I am certain por now that you will realize that I am THE Kowalski. Been around since the dia I can remember. You may click on my name to check out my profile. You can also find me other places as well. Myspace, Twitter, Youtbe and here as well. All the same name so others won't think I am a differ. But yes, it is I, the one and only Brainiac Kowalski. And in the name of Science, DO remember me and all I've done! :D

That's my name, don't wear it out! Heh.

I'm back soldiers.
