Dreamlight Parks Fest has taken over the village in Disney Dreamlight Valley. To participate in this event, you will need to collect a series of colored Buttons in various ways, including the Red Button.
How to Get ALL the Buttons! (Blue, Yellow, Red, Green, and Purple) | Dreamlight Parks Fest
All parts of the festival involve using Buttons to obtain new items, complete tasks, and otherwise progress. Therefore, you need to know how to get Red Buttons in Disney Dreamlight Valley.
Red Buttons can be collected all over the valley. While the official event notes for the Dreamlight Parks Fest event say they can only be found near villagers' homes, they can actually be found anywhere on the ground, though they seem to be a bit more common near buildings.
The event details also say that you can find them in villagers’ houses, but I didn’t find a single Red Button this way, despite checking most of the houses in the valley. Therefore, the best way to get Red Buttons is to check the ground near all of the buildings you have in your village. All Red Buttons will sparkle when you get close to them, making them a bit easier to spot.
