I'm posting this thread to sort of clean up all the cousin data that Aaron, Slo bro and I have previously entered in this forum. This way, Big A's FAQ should be a little easier to write.

I decided to put the locations down by map, because areas tend to repeat.

Finally found all the cousins! Let's keep this thread bumped for everybody who wants it, OK?

For Colombo... I have no idea what a Hydrandrea looks like hehe. I just know that you'll always find him when playing the Octopus' Stage; I think the area is known as the Model Shop. My directions for finding him is to find the hole in the wall while rolling around on the floor; infront of the hole are some of those candies with a face on it and some ninja stars, and on the other side of the hole you'll see some butterflies flying around. So, go through the hole, past the butterflies. Then there should be some big green pots or fat pipe looking things to your left... as you continue further into the room take a left around those big green things I mentioned earlier and you'll see Colombo hiding on the other side of them. He'll have his back towards you...

Bleh, kinda hard to give directions straight from memory but my roomie is playing with the PSP right now :P

he's always in the polar bear stage, too, i think... :peso

In the camel stage on volcano isle how big do u hav 2 b 2 get l'amore?

Was he the one hanging from a bird? I think for him you need around 1m50cm. For the one on the camel you need at least 2m.

Hope this helps, and i hope I had my facts right :S

and welcome! I'm glad people are still playing M&MK.

SloBro- I have been using your gamefaq list which I found via gamespot. Thank you! I was going to suggest a few additions to it, but I can't find any reference to that document on this board. It's called 'me and my katamari presents cousins.txt.' Is it posted somewhere on this board? If not, you might want to post a link. Should I just send you an email with my comments?

I've been trying to get Drooby for 2 days now...I cannot seem to get sent to the Rice State. I've tried the Royal Monument regular and eternal stages tons of times and it seems totally random where it sends you next.

EDIT: Finally got him today, and it's definitely random.
