Knoebel's has Kozmo, which I think is a squirrel. Indiana Beach has I.B. Crow. And I'm not sure he's the official "mascot", but Holiday World has this plump, jolly fellow in a red suit...now what was his name...? ;)
Poor Kenny the Kangaroo seems to be taking a back seat these days to Garfield. Kennywood used to use Kenny, Jeeters and Colonel Bimbo all over the park. There were the costumed characters walking the park; as well as the height measurment signs on rides. Now everything seems to be Garfield. *** Edited 4/25/2004 9:39:50 AM UTC by richmmo***
Kennywood had a Colonial Bimbo too? Isn't Kennywood the park that also had a .. ah ... well ok, I don't feel like typing it over the work servers, but let's just say a female play-thing ... as the name of one of it's mascots? I believe between those two names, you can see why Kennywood's mascots have gone bye-bye.
I believe you could easily find another Colonial Bimbo at BGW (now the ultimate male park) ;)
Actually, Universal has Marvel Comics, Six Flags has the DC characters.

To add to the list, Silverwood has Garfield. That cat gets around. That's not a unique-to-the-park mascot as the original question asked, though; nor are Looney Tunes, comics characters, and the like. *** Edited 4/23/2004 4:28:41 PM UTC by GregLeg***
