You can indeed tame these by using your own health instead of a tame’s; starvation is the most effective method I’ve found so far, as it will heal you for a small amount, nap, wake, and be ready to heal you again by the time you naturally get below ten percent of your maximum health bar due to continued starvation.

if you use a syringe and drain your health to 10% or lower(without dying ofc lol), the pup will try to heal u aswell entering the state in which u can feed it

WARNING: if your tidepup cocoons itself it will lose all of its growth to evolve

easiest way to tame a Tidepup is just to bring a small dino that you can safely injure a little, walk it over to the Tidepup, and let the little guy heal it. Every time it finishes healing your dino, you get a chunk of taming progress. Then you just wait for the Tidepup to chill for a bit, hurt your dino again (not too much), and repeat the process. It’s super low‑stress since the Tidepup doesn’t get aggressive or anything, so you can take your time and just cycle the heal → rest → heal loop until it’s yours.

They are easier to separate for me with a wooden cage. I plop one down and try to get the high lvl one in and once thats in and trapped, i can kill the others. Leave aggro range and come back and its ready to go.

I use a campfire and burn myself down low hp to activate it. It screams and heals me and i can open the cage, feed, close the gate. Rinse and repeat easy peasy.

Use the extended hud setting in your clickwheel it helps with figuring out your hp levels

you will NOT ko him if you try to I will hunt your base down and destroy it you just gotta heal your tames from this dude

You can also hurt yourself with something like a campfire to tame it instead of using a tame.

apparently you tame it by letting it heal your tames?

Youn need to take your dino and injure it down to less than 10% health then ride it up to tidepup and it will do a green heal affect and sleep while sleeping feed it raw meat or kibble soon as ur done u can dmg your dino down to 10% of its health again and just keep repeating the process just make sure u dont hot the tidepup by accident bc it will follow your character while ur injuring your dino if u do it will lose taming and if you stab a second tidepup to get it to go away the one ur trying to tame will run to but just give it a minute then go up to it again it wont loose and taming if you dont take to long
