The Amoeba is an enemy in Rosenkreuzstilette.
Despite the name, Amoebas are actually beings made of water who cling to ceilings. Once the player comes near, they drop down to the grown and glide towards the player. They are based on Puyoyons from Mega Man 4.
They are only found in The Fortress City of Zuverburg (Sichte's stage).
