Jurgen asked "When are we going to stop for the night?"
Mervin said, "Soon. There's an inn we want to get to. We'll stay the night there."
Suddenly they were ambushed by four goblins. A goblin said, "Give us all your money and you won't get hurt."
Jurgen felt himself being transformed. First he shrank to a little mouse causing his clothes to fall off. Then he grew into a huge dragon. The goblins backed away.
Mervin said, "Try spitting fire."
It took a few tries before Jurgen spat fire. The goblins fled.
Mervin transformed Jurgen back into a ten year old and Jurgen started getting dressed.
Jurgen asked, "Why didn't you change them into mice."
Mervin said, "Because you agreed to be my familiar, I can now change you anyway I want."
Jurgen became a mouse again dropping his clothes. Then he became a horse, then a dog, then a woman, then a statue, then back to a ten year old boy.
Mervin said, "But to transform other people or things requires precious mana. I certainly do not wish to waste a drop on four silly goblins."
Jurgen got dressed and they continued on.
