You go to Greg's house and click on the curtain. Then go out side and wait a few moments.
push it with your head

no help
start by clicking on Greg and Greg asks you to help him find his little brother,Manny
Give the guide to Greg and he will continue to help you.
you give him the game guide
he goes to the house to play his video games
Wimpy Wonderland is like the book "Diary of a Wimpy Kid". You must help Greg find Manny before his mom shows shows up! Also drive some teenagers away from a store!
you go to the snow plow truck by the school and offer to help him get the frost off of his windows so he can work.
go inside greg's house and go to the room at the top hand right corner room. Hope this help's :D
Once you have provided the truck driver with the wiper fluid, return to Greg's house and open the blinds to get him to leave with you. You will see Manny drive by in the snowplow truck, and you and Greg follow him to the laundromat (his blanket was there). Push the snowball to bowl over the Whirley Street kids, then sled past them to reach Greg's house. He gives you the Island Medallion for your help.
