The Chao Doctor will examine your Chao. The Chao Doctor will tell you some strengths/weaknesses of your Chao and will explain how it is feeling.
In the modern games, there are two options available when you visit the Chao Doctor: “See the doctor”, and “Medical chart”. On the Dreamcast, there is no Medical Chart option and you can only view your Chao’s stats by using the VMU mini game Chao Adventure 2 - quite a long method!
See the Doctor
An important thing about the Chao Doctor is that he will heal your Chao if it is not feeling well! If your Chao is coughing or groaning, it could mean that it is ill or has a stomach ache. Therefore you should take it to the Chao Doctor and he will give your Chao a pill to take, making it feel much better!
A dangerous glitch exists on the Dreamcast version of the game. Taking your Chao to the Chao Doctor after it has reincarnated can result in the game freezing/data being deleted, so be careful! This is explained more here.
Below are all the illnesses your Chao can get, and medicine that the Chao Doctor will give it to recover.
When you pick the “Medical chart” option, the Chao Doctor will let you read your Chao’s medical records. These records include very detailed information about your Chao! Most of these details can only be seen here. There are three pages in the file which you can switch between (usually this is the L and R shoulder buttons on a joypad).
The blue page shows the basic information about your Chao. You can see the name of your Chao at the top, and a picture of it on the right. The alignment and first evolution of your Chao are displayed on the left; the file refers to them as “Attributes” and “Ability type”, respectively. The bottom of the blue page shows a table showing your Chao’s main stats; Intelligence and Luck are still both hidden. However, you can view your Chao’s stat grades here, and this is the only place you can do so. You should always check the stat grades of all of your Chao!
The yellow page shows some more advanced details about your Chao. First, your Chao’s personality is displayed. This is followed by your Chao’s favourite fruit; try to feed it this to make it happy! Next, the record shows your Chao’s age and its number of transformations. Please note that “transformations” means reincarnations, not evolutions. Finally, this page shows the current condition of your Chao; that is, whether it is healthy or sick.
The pink page shows your Chao’s competitive records from the Chao Stadium. You can see all of the medals that your Chao has won from the Chao Races, as well as its wins, losses, draws, and rank in Chao Karate.
