Patrick is the mayor of Sylvanian Village and everybody trusts him. He's always thinking of things to do for the village and making sure that everybody in Sylvanian Village is OK. 
Margaret is very polite, and is good at teaching the children table manners. She's not prim and proper during her manners lessons - she has such a cheerful smile that even the naughtiest children will listen to her and learn good manners.
Piers has a big appetite - he's always saying "I'm hungry". If he smells food while playing with his friends, he can't help following his nose. His mother Margaret won't let him help get meals ready because he can't keep his hands off the food.
Andromeda is good at listening to her friends and helping them to agree on things.
