Actually what you should have said was "for those that are not familiar with Mayao Miyazaki films" fans would not need a reminder of where it came from.

I think Bloo was in the last pic of that Link ORD showed us. The horn thing might just be something lodged into his head. 8D

I can't tell from the quality I'm watching, but it does look like Bloo is on it at 8:18 - 20.

From what I can make out, there's a Bloo-colored, Bloo-shaped thing there. Prolly drinking out of something he's holding. And the white dots are exactly where Bloo's eyes would have been. The episode also does mention, several times, about using the "imagination". Considering Bloo is an imaginary Friend, I highly doubt they'd pass up the chance to insert Bloo as a cameo/spoof. Can't confirm it though since I'm watching low-qual. :/

edit: oops, never mind. Clearer image here, picture 4.

I've said it before.... It's one of Bloo's BROTHERS!!!!! 8D8D:D:p

FHF has a good point; those "Bloo"s don't even look like Bloo. They could be generic ghost-lookin' characters. :P

Or as T said:

If you ask me, the character in the bed sheet bared a close resemblance to Bloo, except he wasn't colored blue. :-/

From all the "Bloo" sightings I've seen that are up here, I think this could go either way. That thing could have been a tribute to Bloo as a differing version of him, or it could have been a random thing that just happened to look like Bloo.

My bets, however, are leaning on my second guess. The character does look like Bloo, but it's furry and has Ed's horns for some reason. Did the "Bloo" thing speak or was it silent? I haven't seen the episode and I thought this could be another way to tell if it were Bloo or not. If it sounds like him, then it may be a hint about this.

On another note, that thing is adorable.

I think it's quite obvious it's a tribute to Bloo... I mean, the whole episode is called Imagination Land, and somehow I think Matt and Trey enjoy Bloo's humor (because I do belive they watch the show, animators are pretty omnivorous)

Looks close but not him.
