.. Get Kosmo's attention

You would need to reach Kosmos with something. Maybe you can read some clues how to reach higher.

Examine Mom's book. ( The last page and examine the paper. )

You will need:

• A plastic bottle ( There is a bottle in the snow, next to the steam. )
• Another plastic bottle ( There is a bottle in the dumpster. )
• Duct tape ( There's a duct tape in the shack. )
• Something to cut the bottle ( There's a knife in the shack. )
• A pump ( A pump is laying to Jack Frost's house. )
• Water fo fuel the rocket

When you have all the ingredients in your inventory click the piece of paper in the last page of Mom's book.

You can now craft the rocket.

Use it on Kosmos to get his attention.
