How to RescueEdit
First of all, grab an Engine Part and find the ship with the two buttons. After inserting the Engine Part, using Bungalow, shoot the switches to raise the crate. Now, using the grass covered platforms opposite, leap onto the top of the boat and onto the crate, then onto the other side. From here, switch to Chang via the Telepoint and run around the corner, where Feyd is waiting.
