Kermit also made very few street appearances. We all saw him in the series premier and the episode where Slimey goes to the moon but apparently he also appeared in a scene from Episode 295 where he goes 
in a box, 
in Big Bird's nest and a bunch of other places to demonstrate in, out and on but finishes the demonstration 
on Oscar's can
	
	
		
		
	
	
No footage is available but I found this on Muppet Wiki's Twitter page so they might upload at least a small part of the sketch at some point. Also this would have been one of the frogs only interactions with Oscar. He also appeared in a scene from the Put Down the Duckie pledge special where he asks Oscar questions about why he likes public television (the scene was cut on home video releases)
