A sheep.
And like all sheep, inclined to follow somebody. In Beryl's case, it's Jesus. As the physical embodiment of such expressions as "The lamb of God" and "The good shepherd" Beryl's presence suggests that these noble titles are, in fact, teasing nicknames bestowed by those who have seen her galloping after Jesus.
But Beryl doesn't spend all her time with the Son of God. She recently played an important supporting role in Will Shakespeare's new production, "The Satyr and the Shepherd".
She is now also on cordial terms with Adam the unicorn, since he stopped trying to muscle in on her place with Jesus.
Next: Angus.
