Keep yourself dehydrated, have a bunch of stimberries on hand to stop your rising torpor, and you can easily keep yourself at a low enough health to feed them without being risky

(You have to be at 10% or less for them to heal you and then you can feed them)

These guys bout to be the most elusive things on this map

After it heals your tame you have to feed it

Best way to tame, use a bloodpack on yourself so it heals you then just feed it to get his energy back

the 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.
