Caribou Slobber is a clone of Moose Drool. It is an American brown ale. American brown ales are more hoppy than English brown ales. English brown ales are very, very mild almost being bland. I wouldn't call CS hoppy though like a pale ale or IPA.
I have done one CS as a late extract addition brew. It came out tasting almost exactly like Moose Drool. Moose Droll is a pretty good beer but isn't really full of flavor or body. It lacked the deep complex flavors achieved when I had added all of the extract at the beginning of the boil for the first eight or ten brews.
I brewed a CS a couple of months ago with all the extract added at the beginning of the boil and it is really getting good as it matures in the bottle.
