I'll also ask here because it has more fans, but can any of you tell me what the names of the omega trio Humphrey hangs out with?

Here ya go
Salty,shakey,& mooch
Hope this helps :)

Salty: the skiny one with the big nose
Shaky: the little dude with ute hair
Mooch: the fat one that squashes people

I can't give you a straight answer, but I believe the answer could be found here:

If not, then I apologize. But if you don't find the names, I sure there is other stuff on that page you'll find interesting.
And I'm seeing the movie in 2 days, and perhaps then I'll be able to give you the names.

Mooch, Shakey and Salty
