Snoopy is at his dog house at the far left of the island.
He will participate at two parts of the game :
1) Once you have delivered the pumpkin and given the bag to Pigpen and the sucker to Linus. Go to the yard and Snoopy will blow leaves into the pile.
2) After Linus mails his letter, take the pen from his house to the football scene in the yard. Afterwards, pick up the football and knock Snoopy's flying goggles down from the tree, to start the Red Baron scene.
There is no Snoopy Island on Poptropica. Snoopy and "Peanuts" characters appear on Great Pumpkin Island. (see related question)

Go left to Snoopy's doghouse and use the football. It will knock Snoopy's helmet out of the tree.

You click to make Snoopy blow the leaves. You need 5 added to the leaf pile.
After Snoopy blows the leaves into the pile, Linus will jump into it.
Snoopy
Charlie Brown is on the sidewalk when you enter Great Pumpkin Island, but he spends much of the game in his back yard left of Main Street. Snoopy is at his dog house at the far left of the island. Your first task is in the pumpkin patch to the far right. You have to weigh the pumpkins, roll one back to Lucy's house, give Pigpen the bag, and give Linus the lemon sucker. Then you can go left where Charlie Brown is collecting the leaves with Snoopy.

There is no key. Get the mask from the scarecrow and wear it. Knock on the door and you will be at the Halloween party.
