Relationships
Dr. Maddiman

Despite Dr. Maddiman intending to experiment on them, they seem to be quite fond of him.

Initially he was under the impression that they would be happy about being experimented on, and when he realizes that this is not true, and releases them into the wild, they seem hesitant to leave him, Ji-chan in particular stays around the longest before swimming off.

After they turn back to normal from having turned into Gamegosu, Dr. Maddiman apologizes to them, but they quickly forgive him, appearing to be very happy to be with him again.

Abilities and Powers
They're never seen using any special powers, but their combined form Gamegosu is quite strong.

History
In Yo-kai Watch 3 Dr. Maddiman keeps these Experimental Animal Yo-kai with the intention of combining them into a Remodeled Yo-kai.

Afraid of having such a thing done to them, the three escape the doctor's underground laboratory and hide in various sinks around the hospital.

Inaho and USApyon retreive them for Dr. Maddiman, but once they realize just what he wants to do with them, they protect them from him, and make him realize that the Experimental Animal Yo-kai do not wish to be experimented on. Dr. Maddiman apologizes for what he was about to do, and decides to release the turtles into the wild, to be free.

Later, the three Experimental Animal Yo-kai are combined into Gamegosu and are battled by Inaho and USApyon piloting Dainamerashin. Upon being defeated, Gamegosu splits back up into the three turtles, who are then reunited with Dr. Maddiman, who apologizes to them, and aks Inaho if it would be alright for him to take them home again. After some convincing, Inaho decides to allow him to do so, much to his and the turtles delight.

At some point after that, Dr. Maddiman gave each of them a name, and they can now be found together with him in his underground laboratory.
