The kibble for these guys are a real pain to get but there is a way to get the Titan boa eggs to spawn for you. First you must have a argent or quetzal , 2nd you have to build a large pin in the swamp biome about 6 foundations wide and about 40 foundations long. Put a dino gate in the middle of the pin and make all the walls that have windows in them (use gate foundations to place the walls on the outer perimeter) and I made the pin half on water ,half on land. 3rd step is to use the argent or quetzal to grab Titan bias and drop them into the pin. Put about 10-20 Titans in the pin and fly away and come back after a few minutes. The eggs will spawn on the ground so get Argo and have them follow your flyer to once side of the pin. Then simply fly to the side where the eggs are and close the middle Dino gate on the way. It works and was the only way I was able to get Titan eggs. Perfect tame gigantopithecus are super strong and are able to solo any cave. The taming is really fast.
It literally only took me an hour to tame a level 145 with only 50 mejoberries.
1. Gather berries and put the berries in your last slot
2. Kneel down and walk up to one of them and feed it the berries
3. Now you just follow it around while kneeling down and feeding it berries whenever it's hungry
4. Congratulations you tamed one.
Since they're commonly found in the red wood forest, I recommend only taming one if you're close to water as if you get attacked by something you can jump into the water to get away. Then when you think it's safe just go find your monkey and go back to following/feeding it.
