This version is exactly the same as the Sonic Advance 2 garden, except it has a change of one of its mini games. Chao have the ability to fly and swim in the pool.
Notice on the side theres a bar that shows stats, rings, and your Chao's name. The two things you should watch are the mood and Belly. Belly is how hungry the Chao is, don't let this go down much. Mood is how happy your Chao is, you shouldn't let this go down much either. A way to raise your Chao's mood is to pet him or de-weed the garden (weeds are the grass-like things that you see in the picture). It's importent to note that Chao can run away if their mood goes way down, but this is quite rare. Fruit, eggs, and rings obtained in Sonic Advance can be transferred to Sonic Adventure games, but not the other way around. Chao, however can go either way.
There are two games in the Tiny Chao Garden. There's Chao Ball and a Card Matching game. Go to the bottom of the page for a video that shows these games in action.
In this game, there will be red and green balls moving down the screen. You play as the Chao on the bottom who is throwing red or green balls up. When 10 of the same color balls touch, they disappear. Rings are mixed in with the balls, so when the balls disappear rings will fall down for you to get. You lose if you let the balls reach your Chao.
In this game, you see a bunch of cards with pictures of fruit. After a few seconds, they get turned over, and a Chao walks by and pushess them around. If you press the "A" button you can trip your Chao and make him flip over the card (only once can you do that, though). When the Chao is done, you need to match up each card with its mate (there's two of each type of card). Also, if you pick the wrong mate, you lose a life, which you have three of.
To open the store, press the "L" button. There are seven fruit, one egg, and one toy (until you buy all three) sold at all times. There are three toys. The first, a trumpet (1000 rings), the second, a rubber duck (2000 rings), and the third, a TV (8000 rings).
Each fruit raises and lowers stats in a different way. Here is a list of the fruit:
-- 30 rings
