Found the tidepup on astreos on the new island if needed look on wikily for location info but idk if they r rare but can be found, i brought it to my base into a trap brought some dinos like otter and dodo and tamed it that way

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

You can injure yourself by getting bloodpacks and let it heal you for evolution progress. Its not hard but just takes a while, youre also working toward a bloodstalker while getting an evolved tidepup.

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

Rare flowers activate their debuff ability which also counts towards their evolution progress. You can alternate between standing on a campfire and eating rare flowers to evolve them. The wifi symbol on the right is the bebuff cool down and the numbers that show up at the bottom show you the health buffer threshold for the health regen ability. So if you set the threshold to 50 you'll need to take 50 damage to activate the ability. But you'll need to take the damage quickly to reach the threshold. The actual amount of health you have doesn't matter. Once the ability activates the numbers at the bottom will change colors and start to countdown before you can activate the ability again. The number of times you need to activate one of the abilities to get a growth surge seems to change as you progress

You can evolve these safely by putting the tidepup on your shoulder and accessing your own beehive a few times to get low health then sitting on a chair until you heal, then repeating.

For easier evolving: have damaged threshold set to 50. stand on lit campfire next to spikes to maximize damage to enable healing. During the 30 second healing cooldown, step off the fire and eat a rare mushroom to activate dispel.

To get it evolved you have to hurt yourself till it heals you. Best way to do that is to stand in the campfire

30 second cool down after successful healing

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.
