The Knocker, Knacker, Bwca (Welsh), Bucca (Cornish) or Tommyknocker (US) is a mythical creature in Welsh, Cornish and Devon folklore. It is closely related to the Irish leprechaun or clurichaun, Kentish kloker and the English and Scottish brownie. The Cornish described the creature as a little person two feet tall, with a big head, long arms, wrinkled face, and white whiskers. It wears a tiny version of standard miner's garb and commits random mischief, such as stealing miners' unattended tools and food.

We don't need Santa. We have tomten.

The forest elves at Easter
have celebrations every day,
music to the birdsong
and eggs of many kinds:
the very best variety
is golden yellow on the outside
in it are lucky coins
you shall get half a twenty.
Happy Easter!
