One Tooths slowly fly towards Isaac, charging at random intervals at considerably higher speed. They will shy away from Isaac if directly approached.
Notes[]
- Two One Tooths will spawn in the secret crawlspace created by killing
Great Gideon using a Chaos Card.
Variations[]
Fat Bat[]

Fat Bats move slower than a One Tooth but have more health. Fat Bats try to align themselves diagonally to Isaac, giving them a tendency to avoid his shots. They will try to shoot at Isaac once they are diagonally aligned.
