Pavé, the colorful peacock, hosts Festivale every year in Animal Crossing: New Horizons, allowing players to trade in feathers for special themed furniture.
How Festivale works in Animal Crossing: New Horizons explained
If you want to take part in Festivale in New Horizons, then you need to head down to the Residential Services plaza and talk to Pavé.
He ll task you with hunting down feathers and, if you bring him three of one colour, he ll give you a Festivale item.
This item will be the same colour as the feathers you give him, so, if you give Pavé three blue feathers, then expect to receive a blue Festivale flag, stall or one of the other furniture pieces.
What Pavé truly desires, however, are Rainbow Feathers and he ll give you a DIY recipe which will allow you to craft them.
