Bessie Bass

Bessie Bass appears to be a giant Boss Bass (or actually a Big Bertha; see below), and is the middle boss in the third world of Yoshi's Island DS.

When first encountered, Bessie Bass is only slightly larger than a Yoshi; through the use of his magic, Kamek was able to grow Bessie to monstrous proportions.

In battle, Bessie would attempt to attack Yoshi by crushing him with several small leaps out of the water or by making a giant jump out of the water. Then it would fall downward towards Yoshi with its jaws wide-open, trying to engulf him and leave Yoshi with his baby floating away. It is only when Bessie makes one of these large leaps that it is vulnerable to an attack. While Bessie is in the air, Yoshi must hit it on the lips to injure it; hitting Bessie three times on the lips will be enough to defeat Bessie Bass.

In her battle against Yoshi, Bessie is assisted by several Tube Guys, whom Yoshi can swallow for eggs to fight it.

It is unknown if Bessie is male or female - though the English name sounds feminine - and if female, Bessie would technically be a Big Bertha, the female counterpart of Boss Bass from Super Mario Bros. 3 which is of the same species and looks identical to Boss Bass (making her probably the only fish of the species in this game that is female, as the rest all seem to be Boss Basses). Unlike the Big Berthas of Super Mario Bros. 3, though, Bessie cannot shoot young fish out of her mouth, and with her jumping abilities, behaves much more like the males of her species.
