Getting Cape Mario

Cape Mario is generally considered the best Mario.

Cape Mario can fly.
Cape Mario can jump further than other Marios by gliding as he falls.
Cape Mario can perform a cape spin. Cape spin can kill some enemies that cannot be killed by jump, such as Jumpin' Piranha Plants.
Cape Mario can break yellow blocks using spin jump.
He can also flip yellow blocks using his cape spin.
After flying up, Mario can smash down on the ground. This creates an earthquake which kills certain enemies.
If cape Mario is hit he does not die. Instead he becomes small Mario.

Cape is not available until Donut Plains 1.
