Fang

Fangs, also referred to as Bats , are blue bats that have the same mannerisms as Swoops. Fangs appear in the cave levels of Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, Super Princess Peach, Yoshi's Island DS, Yoshi's New Island, and Yoshi's Crafted World. When the player gets too close to one, the Fang will fly towards them from its sleeping position. For unknown reasons, when Fangs fly, they leave a short dashed line behind them. Yoshi can eat Fangs to create Eggs.

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
Fangs appear in Super Mario World 2: Yoshi's Island as enemies of Yoshi which try to damage him by swooping down at him when he gets too close, and are found in the various cave levels. The Fangs tend to loop around as they fly, although this is inconsistent. The official art depicts them as purple, but in the game itself, they are sky blue.

Yoshi Touch & Go
Fangs are also seen in Yoshi Touch & Go, where they patrol ground areas and appear not only in caves, but also in additional areas such as jungles and fields. These Fangs can only be found sleeping on ceilings in cave stages, and are otherwise always in flight, soaring up and down at varying intervals. If shot down with an egg or stomped, these Bats are worth two points, and encasing them in a bubble can earn the player a Blue Coin. In this game, Fangs are purple, matching their original artwork. On a related note, Bats were also present in the Balloon Trip tech demo which eventually evolved into the final Yoshi Touch & Go. In Balloon Trip, Fangs were found in the sky (an area they were ironically absent from in Yoshi Touch & Go) and continually circled around; such a role was taken up by red Fly Guys in the final Yoshi Touch & Go.

Yoshi's Island DS
In Yoshi's Island DS, Fangs return, and are classified as Airborne Enemies in the Island Museum. Despite this, Fangs are seen more in cave areas than in open areas. In this game, they first appear is World 3-5, Heeeeeeere's Wario!

Yoshi's New Island
Fangs once again appear in Yoshi's New Island, with one, named Count Fang, being turning supersized thanks to Kamek's magic mallet, and is the boss of World 2. Count Fang is surrounded by purple Fangs which must be eaten to damage him. Fang's internal filename for this game is "basabasa", sharing this name with Swoop.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
Fangs reappear in Yoshi's Woolly World made out of wool. When the fangs fly they leave long, purple dashed trails in a similar manner to that of running stitch. Fangs also appear in the remake of the game Poochy & Yoshi's Woolly World.

Yoshi's Crafted World
Fangs reappear in Yoshi's Crafted World as rare enemies, only appearing in two levels: Whistlestop Rails and Be Afraid of the Dark. Their wings are now purple like those of Swoops.

Super Princess Peach
Fangs appear in Super Princess Peach. Once again they are enemies which try to defeat the protagonist, but this time it is Princess Peach instead of Yoshi. They appear along with another variant called Glad Fangs and fly right at Peach instead of just around the screen. In several levels, small versions are grouped in clusters which Peach must remove by using the Rage vibe to scare them away. Their wings are now yellow instead of red, while Glad Fangs have red wings instead.
