Chapter 3 Exercise 2 Penguin on a Table

I'm having trouble with this exercise.I did a do together for the penguin to flap wings and go up 1 meter higher than table. But getting the penguin to move to center of table is tricky. When I do a move to or toward table, the penguin goes down towards table top. How can I get the penguin to move at the same height to table center no matter where table might be. I know this chapter is on variables but I'm kinda lost. Any help would be appreciated.
