Here is the Berry Ettin Story:
We are the Berry Ettins. Though we were left on Albia when the volcano erupted, somehow we were teleported onto the Shee Starship Ettin's Revenge. The ship was empty. First we collected as many gadgets as we could find. Then started looking at the genetic files in the egg layer. Something went horribly wrong! The egg layer started creating all different kinds of Ettins. Guess we connected the wrong gadgets.
