The Spongy Speaker Box is a speaker box similar to the Announcer and is based off of the contestant in BFDI, BFDIA and IDFB, Spongy. His first appearance was in "Hurtful!". He has pretty much the same color palette as Spongy.

He last appeared in "Return of the Hang Glider" out of the UFO with all the other different speaker boxes convincing the Announcer to come home with them.
