This is my favourite Bloo episode. I had just recently watched it (from this website, I downloaded it), and it was great.
One of the moments that I really enjoyed was seeing how Bloo tries to make cookies on his own. I also loved Frankie's over-obsession with the cookies. Seeing her scoffling down the cookies and the milk made me laugh!
This is a great episode for showing Bloo how being a rich spoiled 'jerk' (if you will) can't always be fun.
