There are four mysterious beasts that you can encounter in Jedi: Fallen Order. These beasts are stronger versions of difficult animals that you will encounter on your journey. They're all off the beaten track, so you're going to have to explore to find them. Fighting them is easy because they don't have any special techniques or abilities. They are stronger versions of these beasts.
Oggdo Bogdo on Bogano
You can find this creature to the right of the Abandoned Workshop on Bogano, in the Bogdo Sinks. To access it, when you are in front of the workshop, go right crossing two pipes that Cal can go through. To the right, there is a cave that he can enter by jumping through a small space. Use Cal's lightsaber to light up the passage, cutting small pipes in its path. At the end of the cave, Oggdo Bogdo should be walking around his house.
Albino's Wyyyschokk on Kashyyyk
You'll find this big spider at the Imperial Refinery in Kashyyyk. It will be next to the area where several spiders and stormtroopers are fighting. Clean them up, and just before you cross the wall, there's a little path that Cal can go through. Go to the other side, and you will find the spider.
Alpha Nydak on Dathomir
The large bat creature isn't the only formidable foe you need to watch out for in Dathomir. You will find Alpha Nydak to the right of the temple, in the Nightmare Ruins. When you are at the entrance to the temple, go right. You will follow a small path, then cross two walls. When you land on the other side, you will be face to face with the Alpha Nydak.
Rapid Jotaz on Zeffo
The last mysterious beast you can find is on Zeffo. He is located next to the Venator crash site, in the shattered wing. You will need the overload capability of the BD-1 to access it. You will go up a long dark corridor in the boat. When you get to the end, jump and you'll be stuck with the Rapid Jotaz you need to fight.
