Big Bird

Radonkel is a bird enemy found in Super Mario Land 2: 6 Golden Coins. It was the boss of the Tree Zone and guarded one of the six Golden Coins which had been implemented in an egg in Radonkel's nest. The bird attacked Mario by swooping at him. In order to defeat it, Mario had to jump on its head three times. Also fireballs harmed the bird. After Radonkel was defeated, Mario recovered the Golden Coin of the Tree Zone.
