Save Hey Arnold! TJM!

Hey Arnold was one of the most beloved and wonderful children's shows of all time! 

The Jungle movie was supposed to be the second Hey Arnold movie, but because of an argument between Nickelodeon and Craig Bartlett (The creator of Hey Arnold) The Jungle Movie was never made. Tell Nickelodeon how much we love Hey Arnold! and hope they will consider Making the Jungle Movie! 

Note: This section is what is known publicly about The Jungle Movie through chats and interviews done with Craig Bartlett and various other sources.
Arnold's name is revealed in the opening scene. A man comes to the door of the boarding house with a package for him and he signs his full name.

The whole class, who are now in the fifth grade, go to San Lorenzo in Central America after Arnold wins them an essay contest. However, he has his own secret agenda to go look for his parents with the map that he found in the episode "The Journal".

Arnold meets the mysterious Green Eyed People, the people his parents were helping. When he was born, he silenced all of nature (the erupting volcano), which prompted the Green Eyes to believe that he is divine. The Green Eyes have designed a motif that is shaped like a football head in all their architecture. They are also impressed with Helga's ferocity. This makes the Green Eyes semi-worship Arnold and Helga. The Green Eyes also think very highly of Miles and Stella, because they’ve all saved each other’s lives before, many times.

La Sombra, a villain who was briefly seen in the episode "The Journal" is a big character of the movie, he is Miles and Stella's enemy. He is a mercenary treasure hunter and river pirate, who goes in disguise. La Sombra is after La Corazón, a fabulous jewel and a sacred relic of the Green Eyes, which can't be seen in the light of day.

In 2004, Craig Bartlett stated that after Arnold finds his parents he is going to stay with them, but in 2007 he said that they never decided whether Arnold had to stay in San Lorenzo.

Arnold finally takes the next step in his relationship with Helga. While in the first movie she confesses her love for him, but he dodges out of telling how he feels in return. In The Jungle Movie, he completes the conversation. She acts like she still hates him again, but after they "get together" they realize that they are meant for each other. In the end of the movie they share a short kiss (during a scene when they are in a hurry), but Gerald interrupts them. When they make a really lame excuse he says "Whatever you say". By that point, most of the characters in the movie would probably already notice what's going on between Arnold and Helga, and would start teasing them about it.
