The wave starts with a danger zone appearing at the bottom of the screen where a pair of frying pan filled with chikens will appear. (They’re raw and needs more cooking.)

To clear this wave, position your spacecraft when there’s enough space between the frying pan and the chickens. There should be enough space at the center and the left/right side of the screen where your spacecraft can rest.
