Blustering Bellowpane Monster
From Muppet Wiki
Blustering Bellowpane Monster appears in the first season Fraggle Rock episode "You Can't Do That Without a Hat", where he was performed by Tom Vandenberg. The name "Blustering Bellowpane Monster" isn't mentioned on screen; the creature is named in an internal document, The Encyclopedia Fragglia, which was compiled by the cast and production staff.
The character was later recycled in other productions, as Mergie in the video Neat Stuff To Know & To Do and Singalotti in Mopatop's Shop. The puppet also surfaced in Inner Tube and Muppets Tonight.
An earlier, similar puppet was fabricated by Sal Denaro, according to his own records, for The Muppet Movie.
