The seven groups of animals consist of three animals each.Giving animals (or chaos drives) to your chao will increase its stats
Animals are collected in the levels by a character, and able to be given to the chao if you use that or a character on the same dark/hero side (depending on which character you collected animals with in the first place)
If a chao is given an animal, it may (or may not depending simply if you didn't give it enough) gain the animal's appearance, stats, and unique ability. The unique ability can be seen if you watch your chao closely. It may happen rarely, but it is so cute to see it happen!Chao Statistics (Stats)
To increse a chao's statistics, it should be given animals and/or chaos
drives. Chao stats impact performance in races. The highest a chao's
stats can be is 3266 in each category, such as run. power, stamina,
etc. Only chao withan "S" grade for that stat can achieve such a high
number at it 99th level.You can tell the type (color group) of the character by the color in the background of the animal's picture. NOT the color of the animal itself.
