His toads know their owners.

Although the tortoise can know its owner, it is just an instinctive conditioned reflex after it gets used to the owner. When the owner is feeding the tortoise, it sticks out its head, or when the owner approaches, it actively climbs to the owner's side, which means that the tortoises know the owner.

As usual, it is necessary to feed the tortoise regularly and at a fixed point. Ring the bell before the next feeding, and feed it if it walks towards the bell. With this training, the rattle can be used to attract the tortoise.
