Robin Goodfellow, also known as Puck, is a mischievous but often helpful sprite or hobgoblin from English folklore, with deep roots in Celtic and Germanic traditions, representing trickery, domestic help (like the brownie), and shape-shifting, famously portrayed in Shakespeare's A Midsummer Night’s Dream as a jester for Oberon. While primarily English, his character shares traits with the Celtic Púca (Welsh Pwca), a shapeshifting goblin, and he embodies a broader tradition of household spirits and nature-based tricksters found across European folklore, linking to figures like the Irish Pooka or the Germanic Kobold.

Key Characteristics & Roles:
- Mischievous Helper: He might perform household chores (like churning milk) but demands payment in food (milk, cream) and can become troublesome if slighted, playing pranks like leading travellers astray.
- Shape-Shifter: Like his Celtic counterpart, the Púca, he can change forms, appearing as a horse, hog, or other animals, and even as a rough, hairy figure.
- Link to Oberon: He serves as the jester and errand-runner for Oberon, the Fairy King, in Shakespeare's play, making him a central figure in fairy court.
- Nature Spirit: Associated with the countryside, streams, and forests, embodying wild, untamed aspects of nature.
Celtic & European Connections:
- Puca/Pooka: The name "Puck" itself derives from similar Celtic figures like the Irish Púca or Welsh Pwca, known for their unpredictable, shapeshifting nature, highlighting shared folklore across regions.
- Brownie: His role as a domestic helper aligns closely with the Scottish brownie, another helpful household spirit.
- Hobgoblin: He's also known as a hobgoblin, a term for mischievous household fairies.
Significance:
Robin Goodfellow embodies the duality of the supernatural world: a figure who brings good fortune and mischief, reflecting the complex relationship between humans and the wild, magical forces of nature in folklore.
