If the noglin is in water it doesn’t seem to be able to do it’s dash/mind control move. And taming progress will drop pretty fast if in mid tame since it can’t control your creature. Also make sure your pen is air tight
I'm finding that on servers with higher Wild Dino levels, 5 Brontos are not enough for max efficiency. And since Noglins will eat 5 dinos before they lose efficiency, they are impossible to get max efficiency when taming them.
If this is the first time u have tamed one or used one take it straight back to your base and learn how to use it before you try to use it I lost my first one because I couldn’t get out of hunt mode to pick it up
