There are many different collectibles to be found in Kao the Kangaroo, with one of them being Runes. These little stone tablets with purple writing on them will be used to unlock new stages, so they are kind of forced on you to progress through the game. This page will detail the locations of all the Runes found in Hopalloo Island.
Rune #1 Location
Upon completing Walt’s Dojo, you will be right outside of the entrance to the place. Speak to Walt nearby and he will point out the Runes being used to unlock levels, and even show you some of their locations here on Hopalloo Island. If you stand bby Walt and look straight ahead, you should see the first Rune right at the bottom of the stairs, in the open.
Rune #2 Location
Locate the long bridge that has paint on it, which is found in the direction of the windmill. Cross the bridge and go up the hill, where you will pass a building that has a Scroll and Crystal inside of it. Continue beyond the building and to the end of the walkway up here to find this Rune.
Rune #3 Location
After collecting the previous Rune, you can jump down to the beach area below. Look for the fisherman’s hut, which is the smaller one, and on the dock will be the Rune, out in the open.
Rune #4 Location
The final Rune you can get straight after finishing Walt’s Dojo will be in front of the entrance to The Dark Forest. In order to get to it, go back to where Walt was located, then take the stairs opposite of him. The trail should lead up a small incline, which will have two guards, and the entrance to The Dark Forest will be right in front of you; the Rune will be right there in front of the entrance.
Rune #5 Location
You will not be able to get this Rune until you have completed The Dark Forest level. Once you do complete the level, you will exit right next Terror’s Lair, the next path you need to take in the game. A Rune will appear right in front of Terror’s Lair, so it’s kind of hard to miss, should you be paying attention. If you don’t get it then, Terror’s Lair is located behind the one building on the island, by the tables that are sitting outside. Jump up to the ledge from the stump, then climb the ledges in the wall to reach the entrance to Terror’s Lair.
Rune #6 Location
You will not be able to get this Rune until you have defeated Terror, the first boss of the game. Once you have defeated the first boss, Terror, then head to your house (the big building) on the beach and look behind it to find this Rune.
