lol hes mean and i looove him!

well he isn't nice

I'm not sure if he means to be, but 95% of the time, yeah he's a meanie.

sumtimes mean, but i still luv him. (its bloo, not blooh)

Thats why he's one of my favorite characters! :D

He took care of cheese and he woried were he went.

Mean but totally kewl.

Bloo is nice at heart although he looks mean in his naughty behaviour.

hilarious.

hes funny mean and nice all at the same time

Either Way He's Funny especially in "Store Wars!"X3..but I think he's a little bit of them both.

dont get me wrong i love him but hes selfish

Ok, first of all: being mean doesn't always mean that someone's a bad character! Second of all: He's my favorite imaginary friend!

He's mean and nice at the same time

Really, sometimes he can be nice, other times he can be mean. It all depends on who's handling him. He does seem to trend towards doing some really bad things in the last couple of seasons, though...

Doesn't matter if he is nice or mean, he is hysterical as heck!
