Reaper Bird (otherwise known as ",") is one of the many Amalgamates found in the True Lab. It is a very tall figure that appears to be a combination of Astigmatism, Final Froggit, and Whimsalot, while is hurt sound is that from a Vulkin. It summons an Everyman (see more at its definition).
Person 1: So, which Amalgamate is the scariest?
Person 2: I think it's Reaper Bird, but only because of what it did to Everyman.
