(As the credits roll, we see Bloo after eating a serving of "it", he groans)
Bloo: Oh. That's ... it.

Frankie: This is for gluing the furniture on the ceiling. And make sure you leave room for banana hallway and condiment couch.
However near the midpoint of the episode, Bloo never did glue furniture to the ceiling, he broke a series of them in a hallway by using a feather and ingenuity to make a chain reaction.
