He can talk to the person or open up an summonable inventory. The player can then select an item to summon it. Summoning the right items for the right people will make them like QT3 more and will unlock things customizables and dust bunnies. Moving the right analog stick will wave at people, or perform other actions such as dancing if prompted.
On each planet, QT3 needs to complete all of the goals and find all of the presents. L1 shows how many goals are left and R1 shows how many presents are left. Presents can be found using the scanner by pressing triangle and selecting it. This will locate presents but will use up dust bunnies as long as it's active.

There are floating collectibles in space that can be picked up with X. Pressng X over a planet will land there. Pressing X over an asteroid will activate a Dr. Therapist Personality Quiz.
Dr. Therapist
Dr. Therapist holds personality quzzies on asteroids. These present a question and various answers which can be selected from using X, Square, Circle and Triangle. After all of the questions are answered, Dr. Therapist will tell the player something about themselves based on their answers. He will also allow the player to look through each question and see how he came to the conclusions.
