The Grogoch is an Irish fairy which is attracted to human homes. They look like little old men with very smelly reddish hair. It will help out by secretly doing all sorts of chores, usually during the night. You can keep your Grogoch happy by feeding it with a bowl of milk.
Teutor, the Grogoch in Applegate Farm, the latest book in the Antrim Cycle, is lovable and a good friend to the children who live at Applegate Farm.
Here is a sad story about another Grogoch by Fairy Folio.
