- Hookbill the Koopa

Hookbill the Koopa is an enlarged Koopa Troopa in the game Super Mario World 2: Yoshi's Island. He is the boss of World 4 and resides atop the final castle in that world.

''Super Mario World 2: Yoshi's Island
When Blue Yoshi and Baby Mario reach the bridge on which Hookbill is fought, a fog envelops the area, dissipating on the other side. Blue Yoshi and Baby Mario then encounter Hookbill and Kamek. Kamek threatens Blue Yoshi by saying "Little Koopa come through for me now! Go forth and rock Yoshi's world!" and then casts a magical spell on Hookbill. Hookbill retreats into his shell, which grows into an enormous sized Koopa.

After the transformation is complete, Hookbill re-emerges from his shell. Walking on all fours, his creeps towards Blue Yoshi to attack him and Baby Mario. After walking on all fours for some time, he stands up and runs in Blue Yoshi's direction and lunges at the dinosaur. Blue Yoshi then must dodge the attack in order to avoid getting hurt. To defeat Hookbill, Blue Yoshi must first throw Yoshi Eggs at his head or arms. Jumping on Hookbill's shell or head will cause Hookbill to cough up eggs for Blue Yoshi to use should his supply get depleted. After four hits while on all fours or after two hits while on two legs, Hookbill will fall backwards and will be briefly vulnerable to attack. Blue Yoshi must jump on and then ground pound Hookbill's exposed underside, delivering damage to Hookbill. After this (or after a certain amount of time passes), Hookbill will recover, retreat into his shell, and begin pounding the ground. He will then re-emerge, and the process will have to be repeated. Once his underside has been pounded three times, Hookbill is defeated. His shell explodes, and Hookbill falls from the top of the castle.

''Tetris Attack
Hookbill the Koopa re-appears in Tetris Attack as one of Bowser's allies in the game and speaks with a stutter. Here, he takes Phoenix's place of the original Panel de Pon at Stage 9, and unlike other characters, Hookbill does not have a personal ally of his own.
