It is one of the most iconic puppets in the world, and thanks to the efforts of an unknown artist, it may not be around to inspire for another generation.

Jim Henson's monster creations were created by his own hand. The puppeteer used a stick and a puppet head to move a set of puppet hands.

In the famous 1967 film "The Dark Crystal," Henson used less than four pounds of real puppets to tell his story. The original "Henson Creature Shop" puppet stage at San Francisco's Exploratorium was all made with paper, glue and wood.

"One of the scariest things I experienced was that night when they were burning the puppet puppet and the forest crackled with the wood," the late Henson told Britain's Telegraph newspaper. "I thought 'Oh my god, what are we doing? This will kill me.'"

But decades later, no puppets were needed when Kermit the Frog, Fozzie Bear and Miss Piggy came to life. For the Muppets movies, Henson was replaced by a computer, creating frog puppets that had great movement and amazing feel.

Then there's the case of the kid who made a frog puppet of Henson's that happened to take real life break.

According to a paper published by Henson's former managers, by 9:10 in the morning, just minutes after Henson's apparent death, Kermit the Frog began eating the puppet, even chewing for three minutes straight.

"This only played into his constant efforts to prove himself a genius," said Henson's son Brian, who was also one of the puppeteers. "He really wanted to work on the show so much that he was willing to do anything to prove that he could."

According to Brian Henson, he was not sure if Kermit was trying to eat Henson or keep him awake in the body he loved.

The paper also details how Kermit had begun to look a bit human by 8:30 a.m. That night, the Henson family was notified that Henson was alive, but had been told that he "lost his fight for life."

"They were afraid that I was dead, and they wanted to be sure that I was dead, and they were not going to leave any evidence that I was alive, because otherwise they could not keep the job," Henson joked.

When it came time to stop performing on the series, Henson sold his puppet rights to Jim Henson Studios Inc.

So who was the artist responsible for making Kermit the Frog eat Henson's puppet? Actually, it was an unknown student who had years earlier created more than 20 unrecorded pieces of art to show his love for the Henson company.

He called them "Henson's Private Landscapes."
