You know how you get rings by digging with knuckles? Same with "Cutting the grass" with tails? well, in all three adventure fields, there's a body of water, cast around there a few times, and you should get rings and extra lives. unfortunately, no shields sence he doesn't need it. here's were to find the water: Mystic ruins: the lake were you get the silver egg. Station Square: Swimming pool next to the beach or (note: I havn't tryed this) the sewer were tails gets his rocket shoes. Egg Carrior: Swimming pool in a door, on top deck (note: once you drain it, you can't use that anymore).
