There are a total of 21 small animals in SA2 and here's a list of them:
Small animals like penguins, seels will give swim stats to your chao.
Sonic Advance 1, 2 and 3 (Gameboy Advance) have chao gardens which are small and not very great, but Sonic Adventure (Dreamcast), Sonic Adventure DX (GameCube), Sonic Adventure 2 (Dreamcast), Sonic Adventure 2 Battle (GameCube) all have chao gardens where you can do the most things and raise your chao the best and most effective. Sonic Adventure 2 Battle is the most convinient and shows you all you need to know about a chao, and it's a really good game to raise them in by using animals (and Chaos Drives) as a means of training them. Sonic Advance 1 and 2 can connect up to Sonic Adventure 2 Battle and Sonic Adventure DX via a Gameboy to GameCube link cable and you can exchange chao with.
Yes, sonic adventure 2 (dreamcast) and sonic adventure 2 battle (gamecube) are pretty much the same game. However, in battle for the gamecube some scores you need for A rank are different, there are also more characters available in multiplayer and a few other small changes.
Pick up the animal in the chao garden, then walk up to your chao. :l
Find small animals in the stages that raise running stats like: A Rabbit or a Kangaroo.
Carry the ananimal, get close to your chao so that your shadow is near your chao and put the animal. The chao will get the states + you can use it again and again! This can also be used in sonic adventure dx
Give them many skull dogs
You must give your chao every small animal in the game after it reincarnates 3 times. Some animals are only obtainable with certain characters so be on the lookout with everyone.
Make your chao stand still by petting it then grab a small animal and drop it in front of them instead of actually giving them it, if the glitch worked it should look like your chao grabbed it but it didn't and it won't use up the small animal but it will still get the stats! This works in both sonic adventure and sonic adventure 2.
when he small first you give him any habits fast then when he will be big you will see sonic or shadow
game controllers,small screen savers,and of course,a dreamcast
Occasionally when you give your chao the bat small animal it will lose it's legs or actually they are invisible!! To make them reappear give your chao the Skeleton Dog small animal they can be found mostly in pumpkin hill.
