Turtloid S

Turtloid S (タートロイド Ｓ) is an invincible long necked 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 an obstacle. When attacked, it will withdraw in the shell and turn over, 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.

Trivia

 * Excluding the three Mets that appear by using specific Cyber-elves and the three viruses that appear in cyberspace by making a trade with Mega Man Battle Network 4, Turtloid S is the only enemy from Mega Man Zero 3 not to appear in the database.
