For those that are interested - there is a whopping total of 2 pages on the Japanese forums about Pagos. The only posts worth mentioning is that people seem to agree that Pagos is... too bright. And that the Happy Bunnies are stupid.

Something interesting to note is that while browsing other random pages in the thread, there seemed to be quite a few people who actually never liked Eureka in the first place. So much for the Japanese just being goo-goo gaga for mob grinding.
