Hweek

Hweek is one of Tweek's brothers. He can be found in the VAB Building.

How to Rescue
When you start the level, you will need to take the elevator to the Duck above. He will explain that someone has left a child on one of the aircrafts. You will then need to Land the Aircraft. After doing so, the door will open to the shuttle. Go through and find the ladder leading up, glide over to the wing nearest to the room you came from and enter the open door. Hweek is waiting for you.
