Defeating Paavlo
You will fight Paavlo, Drowns, and Burrowers before going on the spaceship. At first you must fight him in sword mode. Keep hitting him and after you get him to about one third health, he sends Drowns in sets of three for four times in a row. After that, you will fight him again. After a little below half health, he will pull out a cylinder with lasers on high and on low (meaning that some lasers are on the bottom and the others are on the top). After that, you fight him again. When he has very little health, he sends out Burrowers in a group of two then a group of three. Fight and defeat him again and he leaves as in the other times.
