This was inspired by an artist on Deviantart however I don't know who he is or who to give him credit so this is the best that I can do.
This is Herbert. He is a Shrog, a mix of a frog and a slug with a hard shell. Herbert weighs 8 oz and is 2 inches long. By his request I'm not going to say how round the little fellow is. His favorite food are mushrooms and more often then not he can be found lounging on a mushroom and ocassionally munching away at it. Herbert is smarter then you may think and he may know something that you don't know judging by the way he's looking at you. Maybe he knows that his mushroom is tastier then anything you've eaten. If you asked him, Herbert would reply with.
'It's for me to know and me alone.'
