After Snoopy gathers the leaves, and Linus jumps in them, follow Linus to the mailbox. You will have to come back to get his blanket from the pile. When he actually mails the letter, go left again to find Lucy with the football and a document for Charlie Brown to sign. (You should have the pen from Linus's desk.)
Charlie Brown signs the document, but she pulls it away anyway. Pick up the football and go left to Snoopy's doghouse. Use the football to knock his helmet down from the tree, beginning the Flying Ace adventure.
After Linus jumps into the leaf pile on Great Pumpkin Island, Charlie Brown is seen getting up from the pumpkin patch where he was waiting all night for the Great Pumpkin to appear. He is disappointed but still hopeful for next year.
After Linus mails his letter, go left to where Lucy and Charlie Brown have the football.
It is Linus that believes in the Great Pumpkin. Charlie Brown thinks Linus is crazy.The great Pumpkin is a figment of Linus' imagination and never shows in any of the Cartoons. Besides...the Great Pumpkin doesn't grant wishes he brings presents.
Charlie Brown is originally outside Linus and Lucy's house, and Lucy is inside. When you complete the pumpkin patch sequence, Charlie brown is with Snoopy in his backyard (left). When you finish collecting the leaves, and Linus jumps in them, follow him to mail his letter. After he does (with a delay to recover his blanket), Lucy and Charlie Brown are playing with the football in the yard.

Although you see him at the start of the island, and in the discussion with Linus about the Great Pumpkin, Charlie Brown does not appear in his backyard until you have completed the Pumpkin selection, Pumpkin rolling, and Pigpen parts of the game. 1) In the Pumpkin Patch, weigh the pumpkins and give the heaviest to Lucy 2) Roll the Pumpkin safely to Linus and Lucy's house 3) Take the bag from Linus and give it to Pigpen outside 4) Give the lemon sucker to Linus and pick up his Pen from the desk Now Charlie Brown and Snoopy will appear at the leaf pile in the backyard.

Charlie brown and Snoopy do not appear in Charlie brown's back yard (to the left) until you have completed the pumpkin rolling process and gotten the party invitation. The sequence of events is: Go to Pumpkin Patch Weigh the pumpkins Roll one back to Lucy's house Get the bag from Linus Give the bag to Pigpen (outside, right) Give the sucker to Linus (get invitation, and pen) Now you can go to the far left of the island, where Charlie Brown and Snoopy are raking leaves.
He is with Snoopy in his backyard, but only after you have gotten a pumpkin for Lucy, a bag for Pigpen, and a lemon sucker for Linus.
The pumpkin patch is both the first and last point on the island quest. You go there initially to see Linus, and return a pumpkin to Linus and Lucy's house. From there you swap Linus's bag for a lemon sucker, and swap that for an invitation to the party, before going left into Charlie Brown's backyard.
You go back to Charlie Brown's backyard. Charlie and Lucy will be there. You have to give them a pen. (Then pen is found on Linus' table after you give him his lemon-flavored sucker.)
He shows up when you first enter the island, getting his party invitation. But you will not see him again until you finish the process with Linus and the Pumpkin Patch. You have to choose a pumpkin for Lucy and roll it safely to her house. Then take Linus's bag and give it to Pigpen, and the lemon sucker back to Linus. Once you have his invitation, and the pen, you can go left into Charlie Brown's back yard where he and Snoopy are gathering leaves.
