Go into te chao garden and go where the stone and water is and go through the waterfall.
The chao who won the race will play with them randomly.
Sonic Adventure 2 for Dreamcast, or Sonic Adventure 2: Battle for Gamecube.
The chao shovel is obtained by beating the beginner race where your chao has to fly you must beat level 3 to get the shovel.
Yes to both questions. In the Chao Garden there is a cave behind a waterfall, if you go behind there you can find two minigames: Chao Race, and Chao Karate.
It is Sonic Adventure 2: Battle. The egg thing is part of the Chao world, it's sort of an extra level where you can raise/race/battle Chaos. It isn't the main game.
You cant take it off sadly but if you win the jewel race it will be a jewel and it would look cooler.
You actually can't plant the seeds yourself, you have to make your Chao do it for you. If one of your Chao wins the Crab Pool race, they get a small shovel as a reward; likewise, the reward for the Stump Valley race is a little watering can. Make sure you have a Chao that has won both of these items. Then hand the seed you want to plant to that Chao, and the Chao will plant the seed for you.
to get to it, complete all the races you have with one chao, then to complete it, in bigginer: your chao has to have about 500 skill in everything. in jewel: your chao must have about 1500 skill in everything. (these are just estimates, just improve skill)
To unlock the jewel race you have to complete all of the beginner races.
you have to win a certain race in beginer race(forget which one) to get the shovel. try to win all the races in beginer race.
At least level 10 or 20.
you race him on your water craft
