Lew Zealand was meant to only appear in that one episode. However, after that, Lew Zealand became a regular character. 
Aside from his boomerang fish act, Lew supplied the Muppets with paper towels in The Great Muppet Caper, played one of the merry men in the Muppets production of Robin Hood, and told Leslie Uggams how to be a great boomerang fish thrower: "Well, you gotta have sole. And if you can't get sole, use halibut."
