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

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.

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

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

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

It prefers the regular kibble from my experience to help tame

It’s a water puppy come on just tame it

Use a syringe (Lv6. 10Hide 1Chitin/Keratin) to lower your health to around 10-15 (each syringe use takes 25 HP and has 5 sec cooldown timer) and these lil tidepod dudes will run up and heal your broken bob butt. After they've healed you, they will take a nap. Once asleep, use the last tab on your hotbar to feed them (kibble is best, but mutton and prime work excellent too). Then BAM, you've got a healer.

To level up there evolution you can pick them up and stand on a fire or use the syringe to keep health low. The more they heal, the more they evolve. You can keep them as a shoulder pet or evolve to a full size saddle rider.

This guy prefers blue kibble(regular) to help tame :)
