To get the key card, put all the bee hives in the houses and then they will open up. Go into the second house at the beginning and on the second level is a chest. Shoot the bees with the slime and quickly use the jump attack to open the chest and pick up the key card.
To get the glue bucket in Who Forest, swing on the limbs and get to the top of the wall of snow. Then go towards the resort until you come to a ledge. Jump to it and break the ice open with the egg shooter. The glue bucket and egg plant are there.
Go straight ahead when you start at Who Lake, until you come to the part where you have to swing up the mountain. At the top, use your jet pack to blast up onto the roof and drop down the chimmney. Breath on the fat man until he tries to shoot you and then breath on him again. Repeat this untill he falls and then pancake him to get his shirt. Now he will charge so lead him into the wall by the dear head. Take his pants.
