he is on the sidewalk happy cause he got an invitation to the halloween party
To get the pen for Charlie Brown in Poptropica, you need to retrieve the pen from the map in Great Pumpkin Island. First, find Lucy's psychiatric booth and talk to her. She will ask you to find Linus, who is sitting outside the school. Linus will give you the map with the pen on it.
you go into the kid with the blanket's house when he is done writing his letter to the great pumpkin. when he is done you go to the desk and take the pen off of it.
It is in Linus's house on the desk.
By snoopy's doghouse
When you go to the far left later in the game, Charlie Brown needs to sign a document and he needs you to get a pen for him to do so. See poptropicasecrets.com
You get the pen in the BLUE house. Then you walk back to Charlie Brown [ be right next to him!] and click on the little brown pack in the corner of your screen, find the pen, and click USE. HOPE THIS WAS HELPFUL! :-)
You give it to Charlie Brown, and he will sign Lucy's contract
you go to linus and lucys house after or while you give linus a lemon flavored lollipop and its will be on the desk.
you go to the girl with the blue dress A.K.A Lucy and she will say to the boy with the yellow shirt with the black stripe A.K.A Charlie Brown and she will talk him into signing a piece of paper but Lucy and Charlie don't have a pen therefore you have to press use when ur next to Charlie Brown and there you go :)
you pick up the ball and use it near snoophie the dog,you will find snoophie glasses there are on the tree
I'm pretty sure later on when Lucy and Charlie Brown are about to kick the football, Charlie Brown needs a pen to sign the document saying that Lucy won't mess with him.
go to linus's house and walk by his desk then click on charlie in the backyard
