Boss: Egg Albatross
                The Egg albatross is and upgrade from the "Egg Hawk." Dodge the bullets it shoots at you. Then run up to it with.....
Sonic. He can run up to it, jump and keep jumping on it.
Knuckles. Run up to it and punch or throw fire balls at him.
Tails. Keep shooting at it with thunder shoot.
What made it go fastest for me was using Sonic.
             
                        
                Boss: Egg Hawk
                To defeat the Egg Hawk, you have to run up to it and attack it (sonic recomended). Dodge the bullets it fires at you. Sometimes it lands in the middle of a circular platform. Run up to it (Knuckles recomended) and attack it. (Or use the team blast to make it go really fast. (Optional)   Everytime you go past a circular platform, you see a box. Break all the boxes and you will get 1 power-up.
