Hooktail

Hooktail is a dragon that's been terrorizing Petalburg and eating many of its residents who came to her castle to slay her, like Professor Kolorado's dad and Koops' dad. When Mario, Goombella and Koops came to her castle to obtain the first Crystal Star, the Diamond Star, they learned she got food poisoning from something that starts with cr- and ends with -icket. They learned her weakness was the sound of a cricket's chirp. Upon reaching the tower, they slayed her and freed Koops' dad, who was swallowed whole and obtained the Crystal Star, which Koops' dad found in her stomach. She has two older brothers named Bonetail and Gloomtail. Bonetail resides in the bottom floor of the Pit of 100 Trials and Gloomtail guards a key in the Palace of Shadow.

The holder of the Diamond Star is the dragon Hooktail. She has no problem with eating the innocents in the audience( and does so when she is low on health), but she claims to have gotten food poisoning from eating crickets once, so she becomes ill upon hearing the sound of crickets. Mario and co. can use this to his advantage by using a badge in Hooktail's castle that makes his attacks sound like crickets. This badge is found in a dungeon beside a pile of bones where Mario must first use his new learned ability to turn "paper thin" and walk between the cell bars to recieve the badge (uses 0 BP). When he does so, her attack is decreased from 5 to 2, and her defense is decreased from 1 to 0, making a boss that is virtually invulnerable and nearly impossible to survive at this point in the game a manageable opponent. Hooktail attacks with fire breath, biting attacks, and stomping moves. Hooktail has two brothers named Bonetail and Gloomtail, who live at the bottom of the Pit of 100 Trials and behind the Thousand-Year Door, respectively. The two have the ability to inflict status ailments with their breath, and additionally, Gloomtail is able to charge up for his double-strength "Megabreath" attack, and Bonetail is able to heal himself at will.
