The player controls Billy, who cannot do much by himself aside from moving and jumping. However, his abilities greatly expand while holding an egg. While rolling an egg, Billy moves faster and is more agile. He can also perform several techniques with an egg, such as egg dunking, slamming, dashing, and shooting. Eggs The game features 72 different eggs to hatch, most with unique designs. As Billy rolls over fruit collected from the world or dropped from enemies while holding an egg, the egg will grow in size and power. When the egg's gauge completely fills, the egg reaches a maximum size and flashes, indicating it is ready to hatch. Billy can perform a rooster call to hatch fully matured eggs, which can hold contents such as helper animals, hats, and items. Certain eggs are required to hatch to progress through the game, as they are necessary to clear objectives or get past obstacles. Eggs can be damaged by enemies, large enough eggs, and the environment. An egg's damage is represented by cracks appearing on the egg's meter in the corner of the screen. When the egg takes enough damage, it is destroyed and nothing hatches from it. Eggs can also be 'lost', i.e. put into positions or situations that the player cannot retrieve them from. In such cases, the egg will disappear from its position after several seconds of inactivity and will appear back at its nest at its smallest size. Eggs with a Sonic Team logo on them can be found and hatched in certain levels after collecting enough chick coins, holding animal friends of Sonic Team characters such as Sonic the Hedgehog or NiGHTS. Eggs will grow at a faster rate depending on the size of the fruit collected. Some eggs are easier to hatch than others, and require less fruit than others. Eggs that contain items usually hatch faster than animals, with the exception of eggs which contain Game Boy Advance minigame download titles. Levels Morning Land is divided into seven stages, the first one being Forest Village.
