[...]

- No, I mean a real monster, like a huge enormous deer. Except they say it's got a human face sometimes and then at night they say it...

- Aaah! Where'd it go?

- Would you be kind enough to grant us passage through your forest, little one?

- Sir, I really think we should turn around now.

- There's a lovely trail back across the river.

- The current's too swift for us to get across.

- And your friend's injuries are very bad. If we don't get him back soon, he doesn't have a chance.

- Hey, little fellow, are you showing us the way or just getting us more lost?
