It is NOT a knockout tame. Use a torch to lure it in, then do whatever it says (just know it's XP related, like crafting, killing, etc) after you fill the bar up, you feed it using the last slot of your inventory (duh) keep repeating this and it will soon tame! Have fun, don't die!

While taming it, don’t hop on a mount or go in the water. This will make it hop off your shoulder and interrupt the taming process.

To tame, use a basic torch. I’ve found that if you have a cosmetic equipped to the torch (like the sparkler skin) it won’t land on your shoulder. I couldn’t figure out for the life of me why it wasn’t working, even after clearing some dinos out and harvesting corpses. After doing that, I've tamed quite a few. So yeah! Happy taming 😊

Equip a torch it will land on you and give you tasks complete

The spring drakeling requested you earn exp by doing tasks

Crafting

Harvesting

Or killing dinosaurs

You have 2 mins to complete the task then you feed it meat and repeat till tamed.

Approach with a torch out and it will land on your shoulder. It will then require you to gain a certain type of XP. So far I've come across crafting, harvesting and killing as requests. Once your XP fills the bar to 100 you can feed it exceptional kibble from the last slot of your hotbar. Rinse and repeat until tamed.

If you are having troubles getting this thing to land on your shoulder try taking off all your armor first then pull out your torch and just stand close to it. After it lands on your shoulder put your armor back on and follow the prompt given on screen to start taming your new little buddy

From what I can tell there are 4 different types of these guys found at different areas of the map. To tame them you take a torch and stand under it and it will land on your shoulder. Once it is on your shoulder you'll be given task to complete such as kill experience,craft experience,harvest experience. You will be given a timer to complete each task and if you don't the tame effectiveness will decrease and the drake ling will jump off your shoulder. Make sure to have mutton(you can use any meat) or exceptional kibbles in your last hot bar slot as you will need to feed your drake ling after you complete each task. Rinse,wash,repeat and you have a drakeling.

They prefer Exceptional Kibble (Yellow one)

Equip a torch to bring the drakeling to you, and then follow the prompts within the time limit to feed and gain taming progress.
