Large Marvin Fraggle

From Muppet Wiki

Large Marvin is the fattest Fraggle in Fraggle Rock, due to his love of snacking. He is a bit dimwitted, but is also athletic and a feared swimming opponent of Red Fraggle.

His first appearance was in the Fraggle Rock episode "The Beast of Blue Rock."

Large Marvin was later seen as an audience member on Muppets Tonight.
