Turtloid S

Turtloid S (タートロイド Ｓ) is a invincible turtle enemy with a spiked shell that appears in Volteel Biblio's Sunken Library stage in Mega Man Zero 3. It only floats stationary in the water as a obstacle. When attacked, it will withdraw in the shell and turn around, allowing Zero to use it as a platform to avoid the electricity of the water. It will turn back to normal after a time, hurting Zero if he stands too long on it.
