pickyulas for the boss in level 4. They attack and hold you for 6 seconds.
To attack them, slice their bellies and keep on slicing them til they're dead.
If you stop attacking them, they will turn back over. Their back is hard but
they have soft bellies. They make snorting sounds. Even endermen can
kill pickyulas. They kill and eat Pickyulas. Never let pickulas attack you!
They are dangerous!
